Camping Axe or Hatchet

One of the most useful tools in camp is a good axe or hatchet.  It doesn't matter whether you're camping in a luxury RV or roughing it in a tent.  Both lifestyles enjoy campfires and a good axe or hatchet is a valuable tool for cutting and splitting firewood and preparing kindling. 

A hatchet is small axe, often used with one hand where the larger axe takes two hands.  One of the most versatile hatchet configurations in my opinion is a roofers hammer, which has a hatchet blade on one side of the head and a hammer on the other.  The back of a regular hatchet or axe can be used for driving tent pegs or splitting wedges, but he hammer head is more precise and is easy to use as a hammer.

Axes come in many sizes.  They may have a single or double sided blade.  The larger the axe, the heavier it will be making it both harder to swing and capable of making deeper cuts.  I like a fairly small axe for camping, one with about a 30" handle.  It isn't too heavy and it fits well in RV outside compartments.  For tent camping I prefer a hatchet, which fits easily in my camping bins.  A large, double-bitted, "Paul Bunyan" style axe is useful if you're doing any heavy felling or cutting, but they are big and heavy and in some ways the extra blade seems to be more dangerous.  For normal campfire activities such an axe would be excessive,  take more energy to use than it might be worth, and be cumbersome to store in RV compartments and camping bins.

No matter what size axe or hatchet you choose, you will need to keep it sharp.  Sharp tools are not only easier to use, they are safer.  It is a good idea to put an edge protector on the blade to keep it from being dulled by rubbing against things in storage.  Axes and hatchets can usually be sharpened on an electric grinder.  Just be careful not to spend too much time in one spot because that can overheat the metal and ruin the temper.  Hold the tool so the blade is tangent to the grinding wheel and move it back and forth smoothly to shape a neat taper on each side.  Grinding is usually sufficient for sharpening most axes but you could finish it with a file or even a sharpening stone if  you want an especially fine edge.

Handles should always fit tightly in the head.  Loose handles are dangerous.  The head could fly off at any time and inflict serious injuries on anyone it hits.  A loose head also messes up the precision of your cutting strokes and reduces the efficiency of each blow.  Wooden handles can usually be tightened by driving wedges into the end of the handle at the head so it expands the wood to fit tightly in the hole in the head.  Metal or fiberglass handles usually don't come loose and may need replacement or servicing by a qualified expert if they do begin to tail.

Handles should be clean and smooth.  Some hatchets have rubber or leather wrapped  handles for a better grip.  Wooden handles should be checked for cracks, rough spots, and splinters.  Rough spots should be sanded down, splinters trimmed and sanded, and the entire handle treated with linseed oil or a good quality furniture oil.  Don't over oil the handle!  You don't want it to be slick.  The oil should penetrate the wood, not create a slick, glossy coating.  When oiling the handle, use a soft cloth to rub the oil well into the wood.  You might also rub a light coating of oil on the iron head as well to prevent rust, especially if you're putting the tool into storage for a while, like at the end of an outing.

Chop, chop!

Camping and Survival Knives

"A knifeless man is a lifeless man".  This old saying may indeed be true in a survival situation.  A knife may be the single most useful tool you could have -- other than your brain.  That being said, the question may arise "what is the best knife?".  There are many different sizes and styles of knives and each one has its own special niche.  In recent years there have been a proliferation of "Rambo" style survival knives promoted on the Internet and marketed through outdoor stores -- huge knives with mini survival kits stored in the hollow handles.  No doubt these have a certain appeal but how well would they work in a real world survival situation?  The tiny plastic compass is probably better than nothing, but how long will it last?  And what will you really do with a couple feet of fishing line and a few safety pins?

The best consensus I've found for a good survival knife is that is should be a bit more modest than these monster combat blades -- a 3-4" fixed blade is usually recommended as best for survival.  The reasoning is that in a camping or survival situation you will do a whole lot more carving than you will hacking.  Sure, having a big, heavy knife may be useful when building a shelter from tree limbs, but how often is that going to happen?  And, even when you do need to build such a shelter, you probably will only do it once per event.  On the other hand, there will be an ongoing need for carving. Even notching limbs to secure cordage in building a shelter will require more finesse than hacking power.  Any kind of medical applications will need a fairly delicate blade.  Skinning and butchering animals for food or other uses will be well served by a modest blade.  You will also need a modest blade to carve wooden tools and implements.

Multi-tools are often touted for camping and survival use.  One cannot deny the versatility of these items or the convenience offered by the multiple functions they are capable of performing.  About the only downside to a multi-tool is that it has folding blades, and folding blades are not as sturdy nor as safe or as  durable as fixed blades.  Locking blades will mitigate this problem to some extent, but the ideal blade for camping and survival will remain a fixed, 3-4" knife like a hunting knife.  Having both a proper knife and a multi-tool would be a particularly good combination.  Having both for camping should not be a problem for most people.  They need not be especially expensive and they take up a little room in your pocket or pack or on your belt.  Carrying both on your person at all times so you have them in a survival situation may not be as convenient so you may have to make a choice.  I have recently seen a specialized knife that includes a built in flint and steel fire starter, which strikes me as a really good starting point for any survival situation.

Having a knife -- the right knife -- is only the first step.   For it to be really useful (and safe to use) it must be sharp.  Yes, a sharp knife is actually safer to use than a dull one.  It is worth learning how to hone a knife edge to keep it sharp.  The most common and traditional way is using a sharpening stone but there are other types of knife sharpeners, like the drag through manual kitchen knife sharpeners and electric models that use internal grinding wheels.  You may be able to improve sharpness using one of these but to get a truly fine edge requires a practiced touch on a sharpening stone.  There are several tricks used by those who know how to do this well.  Using a combination of wet and dry sharpening is one.  Another is to push the knife toward the stone as if you were shaving it instead of dragging the edge backwards on the stone.  To get a good edge you need to hold the knife at the right angle to the stone.  The angle will depend on the thickness of the blade and the basic shape of the taper so you will need practice to find the right angle for each blade.  It is rather tedious endeavor but well worth the effort. Here is a link to a really good article from Buck Knives on How To Sharpen Your Knife.

The bottom line:  my personal recommendation is to carry a 3-4" fixed blade knife as the basic tool in my camping and survival kit.  And then supplement it with a multi-tool and a flint and steel fire starter -- and a sharpening stone.

Look sharp!

Candle/Flower Pot Heater

Someone emailed me a description of a candle/flower pot heater.  The article claimed it could heat a small room (like an RV or a tent) for 15 cents a day.  Right!  If it did, wouldn't everyone be doing it?

The idea is that nested clay flower pots placed over the candle (or candles) act as a radiator to capture and distribute the heat of the candle(s).  That may, in fact, work to some extent -- that is, it will capture and hold the heat and you may feel it more if you are close to it than you would just being the same distance from an open candle flame.  However, the idea of heating a small room with a candle is ludicrous.  It is simply impossible.  A candle only puts out from 30 to 77 watts of heat.  It would take a lot of candles to match the output of a typical 1500 electric heater, which, if used 10 hours a day would cost less than $1.50 per day with electricity going for less than $.10/kwhr.   Stacking a bunch of flower pots on top of some candles will not multiple the heat.  In fact the pots may capture heat you could otherwise be enjoying.  Remember your basic physics:  energy cannot be created or destroyed (although it can be lost, as in losing heat through uninsulated windows).

So why is this in a blog on RVs and OHVs?   Well, one of the videos I found online showed a guy testing a flower pot heater in a motorhome.  He had closed off the main salon so he was only trying to heat an area of about 8' x 15'.  He tried using one large candle, using 4 tealights, and even using the burner on the stove.  In one documented test, the measured temperature inside the motorhome started out at 68° when he lit the heater.  A little more than two hours later it was 64°.  What happened was the sun went behind the clouds so he lost any solar heating that might have warmed the interior to 68° and clearly the candle wasn't contributing much, if anything, to keeping it warm.  The flower pot did get warm to the touch, which could be useful if your hands were cold, but I' rather wrap them around a cup of my favorite hot beverage.

Too bad it doesn't work.  It would sure be nice to have a simple, inexpensive, auxiliary heat source for our RVs.  If you really need to supplement your RV furnace, try using an electric heater or a propane powered catalytic heater.  Hey, even your trusty Coleman lantern will do a better job of warming up your RV than a candle/flower pot set up!  That's all one of my friends ever used to heat his Class B van conversion.   If you have shore power or are willing and able to run your generator, the electric heater option is clean and easy to use.  Portable catalytic heaters are also simple, but you must keep a couple of windows slightly open to provide sufficient ventilation so you won't suffocate.  Even heaters that are designed for indoor use and purport to not give off any toxic fumes WILL consume oxygen and without adequate ventilation you will die!

We can put candle heaters in the same category as Mountain Dew light sticks -- a cute idea that doesn't work!  You'll find articles on the Internet that promote both of these ideas, but you will also find plenty of articles that debunk them.

Don't get taken in!

Wet Wipes

We're always looking for more convenient ways to improve our camping experience.  We like tools and appliances that are lighter weight and easier to use.  We like tents that are easy to set up.  Of course, camping in an RV is all about convenience.  But there are little things that can boost convenience too.

Wet wipes have long provided added convenience for the messy task of changing baby diapers.  They can also be very useful when camping.  There are many different types of specialty wipes on the market today, ranging from hand sanitizers to tire shine.  There are general purpose cleaning wipes that find many uses at home and around camp.  But to get the most out of wet wipes, check out the ones designed for specific needs you may have in your RV or while camping.  Wet wipes often take up less space and are more convenient to use than liquid or aerosol cleaners.  Sometimes you can even tuck them in your pocket or pact for use out on the trail.  If they come in individual sealed packages like the ones at restaurants, keep them sealed until you need to use them.  If not in individual packages you might be able to seal them in a Ziploc type plastic bag so they stay moist.

Here are some of the types of wet wipes I've seen that may be helpful:

    * General purpose wipes
    * Baby wipes
    * Glass wipes
    * Furniture wipes
    * Leather wipes
    * Tire wipes
    * Stainless steel wipes
    * Counter top wipes
    * Hand sanitizer wipes
    * Mechanic's degreaser wipes
    * Antiseptic wipes

While general purpose wipes can handle a myriad of tasks around camp, there are some places special purpose versions will definitely shine.  Baby wipes are especially gentle for cleaning sensitive skin on baby's of all ages.  Glass cleaners won't leave residue and streaks on mirrors and windows.  I don't find the little towelettes very good for cleaning big vehicle windshields but they're perfect for touching up rear view and shaving mirrors.  You will want to use leather wipes on your leather upholstery and to clean your shoes and saddles.  They are formulated so they don't try out the leather but do have additives to help keep leather supple and add to the shine.  Tires wipes are quick and easy way to add shine and protection to clean tires and rubber trim.  Stainless steel wipes are perfect for the comparatively small sinks and stoves in RVs and take up a lot less room than a big can of aerosol stainless steel cleaner.  Hand sanitizing wipes are a convenient way to protect yourself from germs at picnics and when you stop for meals on the trail.  You might even tuck a couple of mechanic's degreaser wipes into your tool kit or fanny pack on OHV trips.  The whole packet will probably be too big but for each trip you could put a couple in a Zip-loc type plastic bag.  They might not be as a effective as Goop cleaner and warm soap and water but they will get off a lot of the gunk that would otherwise end up inside your expensive riding gloves.  Don't count on them staying wet for more than about one ride, even in a plastic bag.  Antiseptic wipes are perfect for cleaning around small wounds before applying a Bandaid and cleaning your hands before eating out on the trail.

One word of caution:  don't put wet wipes, even so-called flushable wipes, in you RV toilet or Porta-potti.  They won't break down fast enough or well enough for complete flushing of the tanks when dumping. 

Most wet wipes come in some kind of resealable container.  Be sure to close all plastic lids completely.  The pop-up feature is handy, but it often leaves enough of the next towelette sticking out to get in the way of proper sealing.  When that happens, they will dry out and become almost useless.  Flat packets often have a resealable flap.  I've found that if I store them with the flap down so the packet is resting on the flap it helps prevent the contents from drying out.  The weight of the remaining product helps keep the flap closed tightly and gravity brings moisture to the bottom so the next wipe is plenty moist.  If you store them with the flap up you'll probably find them pretty dried out in just a day or two.  For those with Zip-loc type seals on the end about all you can do is make sure it is completely sealed.

Antiseptic wipes usually come in individual packets for single use applications.  The nurse in your doctor's office probably uses one to clean your skin before giving you a shot or taking a blood sample.  It would be a good idea to have a supply of these in your camp kit and carry a few in your personal pocket first aid kit whenever you are out and about.

You may also encounter single use wet wipes at restaurants who serve "finger food".  They are helpful both for pre-cleaning  your  hands before eating and getting rid of the sticky residue afterwards. If you have some left over, tuck them in your pack or pocket for use on the trail.

Wipe out!

Winter Dirt Biking

Dirt bike riding isn't nearly as popular in the winter as it is in the summer.   When we lived in sunny southern California, winter outings weren't usually too bad.  We did encounter snow on a couple of occasions, but mostly we didn't have to deal with temperatures much below about 40° F.  However, even 40° is cold enough to make one begin to question the sanity of being out on dirt bike.  And I've never found riding anything with only two wheels much fun in snow!

As with any other cold weather activity, the key to staying comfortable is dressing right.  Dressing in layers is definitely the right (or only) way to go.  Start out with some good thermal underwear and warm socks.  I always wear two pair of socks in my motorcycle boots winter and summer.  A pair of light weight dress socks avoids blisters and the thicker cushioned motorcross socks absorb impacts and help keep my feet warm.  Make sure your boots aren't too tight.  Tight boots will restrict blood flow and your feet will freeze!  For most of our California riding, ordinary riding pants over thermals were pretty adequate but regular jerseys were too cool under our Enduro jackets.  If you expect really cold temperatures you might double up the thermals or wear some sweat pants under your riding pants.  You could wear a sweater or sweatshirt as an extra layer under your jersey but we found that "Windchill" jerseys did the job without the extra bulk and restriction of movement of added garments.  Together with either glove liners or Windchill gloves, an  Enduro jacket, and a nylon face mask were pretty much all that was needed.  It if got really cold, a warmer motorcycle coat did the job.

Snowsuits, like the ones you wore as a kid or like the ones worn by snowmobilers will keep you warm in pretty cold weather, but I've found it more comfortable and convenient so simply dress in layers.

Glove liners often cost almost as much as the gloves themselves.  We found we could use fairly inexpensive (knit gloves) under our normal riding gloves and they kept our hands pretty warm.  Sometimes even got them two pair for $1.00 at our local dollar store.  Windchill gloves were usually quite comfortable without any additional liners at a little more than the price of regular riding gloves.  Bulky winter work ("polar") gloves were very warm but are too clumsy for handling the controls and ski gloves,which are warm and flexible, don't  provide enough protection against brush.  If you hands are still cold you might try glove lines under windchill gloves.  Or get some "Hot Hands" chemical hand warmers.   You can use similar chemical warmers inside your boots to keep your feet warmer too. They even make pads large enough to warm you back or your tummy.

Road bikes and snowmobiles have electrically heated hand guards and gauntlets that might be adapted to dirt bikes, but the extra wiring might be prone to get caught on bushes and the magneto on dirt bikes may not be able to supply enough power for the heating elements.  I've tried electrically (battery powered) heated socks but didn't find the performance worth the extra weight of the batteries.

You should feel just a little cool when you're ready to ride.  If you're already warm, you're going to get TOO warm once you start riding.  Although bipping along at a stiff pace will add a bit of wind chill, your physical exertion is going to warm you up to the point where you'll need to stop and start stripping off layers before you get soaked in sweat if you are dressed TOO warm to start with.  If you start out warm and cozy you will get too warm and start to sweat once you get going, even with the wind chill but those two narrow tires are still pretty skittish.  I've even seen guys try riding with sand paddle tires in factor.

Dirt bikes aren't very stable in the snow.   I've seen some guys use studded tires to improve traction, in deep powder snow.  Sometimes running a lower than usual tire pressure will improve traction a little bit.  But, basically dirt bikes are made to ride in the dirt, not the snow.  ATVs, with their softer, fatter tires and 4WD are a lot better adapted for getting around in the snow.  And, of course, snowmobiles are a blast!
When you get back to camp, get out of your cold and possibly damp clothing as soon as you can and swap it for something warm and dry.  I keep an old pair of puffy snow boots I call my desert slippers to change into to quickly warm cold feet and keep the chill off.  A steaming cup of your favorite hot beverage next to a blazing fire will also be a pleasant way to chase off any remaining chill.  Or get inside  a warm tent or RV.

Stay warm!

Camping Supplies from Dollar Tree

I am a strong proponent of looking for camping and RV/OHV supplies everywhere I go.  I have found bargains at drug stores, farm and ranch stores, and grocery stores as well as at RV, OHV, camping, and outdoor outlets.  You can often find things you can use for camping in your own basement, attic, or garage.  One kind of surprising place I've found is my local dollar store.  The solvent resistance foam tiles on the counter of my enclosed motorcycle trailer are kids animal puzzle tiles from the 99 Cents Store in California.  I was teased a lot when my riding buddies first saw them, but they sure changed their tune when they saw how well they worked!  We get most of our cleaning supplies, toiletries, sundries and OTC medication from Dollar Tree along with flashlights, batteries, and many kitchen utensils.  Paper goods, plastic utensils, etc are also readily available.  The cheap single ply toilet paper is a pretty good substitute for the more expensive RV tissue and a lot more compatible with holding tanks than the fancy quilted brands.

I've mentioned Dollar Tree and other dollar stores in several places in this blog.  Not long ago I found a camping article on Pinterest that also entreated readers to shop their local dollar store for camping supplies and things to keep kids occupied.  There were come negative comments in response to her presentation.  As with anything you buy, you should make your own decisions and buy what works for you.  Like me, the writer touted the advantages of dollar store flashlights and batteries.  At least one reader rejected her advice.  He preferred to buy sturdier flashlights that lasted longer.  I stand by my original recommendation of using dollar store flashlights and batteries, especially for kids and loaners.  Like the critical reader, I like to have a couple of high quality Maglites for my own use, but have found it particularly advantageous to use inexpensive and easily replaceable flashlights for kids and loaners.   Those light weight plastic flashlights may not be as durable as nicer ones but, hey, I'm not out serious $ if they are damaged or don't come back.  I was really ticked when one of my kids "borrowed" my good blue brand new anodized Maglite for cave exploring and brought it back looking like it had been through a rock avalanche.  The good news?  It still worked just fine.  It just wasn't very pretty any more.  No doubt a cheap plastic flashlight would have been left in pieces in the cave. But at least I woudn't have been out much!

Many of the cleaning products at dollar stores are brand names so often there is no question about quality.  However, don't reject their own house brands or off brands.  My wife and I have found than many of the "Awesome" branded products at Dollar Tree are excellent and match or even sometimes exceed the performance of similar brand names.  In addition to liquid and aerosol cleaners you can often find a variety of wet wipes.  I've found leather wipes, tire wipes, stainless steel wipes, furniture wipes,glass wipes, and mechanics' degreaser wipes in addition to traditional baby wipes and general purpose wipes.  They seem to come and go so I advise stocking up on what you want/need when you see them.

OTC medications are another category I find Dollar Tree to be a good source for.  It enables me to easily and inexpensively stock my medicine cabinet with a variety of choices so all member of my family or group can chose their favorite pain relievers, etc.  Aspirin doesn't work for every one so I carry

acetaminophen and Ibuprofen too. Nice not to have to shell out big bucks for each bottle.  Since stuff in our RVs and camp kits often sit around a long time before being used it is also nice not have a large investment in disposable items that may have to be replaced periodically without being used up.  Fortunately, most medicines are good long after their official expiration dates, but if you have any concerns, it is inexpensive to replace them at Dollar Tree and maintain peace of mind.  I have found surprising number of different types and sizes of bandages and medical tape.  And I keep a tube or two of Superglue in every one of my first aid kits.  Superglue is almost the same thing as pharmaceutical grade "Dermabond", but a lot cheaper, especially when you get it at Dollar Tree.  In use it may sting a bit more than Dermabond, but it will essentially work just as well at holding small wounds together.  And it bonds instantly to skin.

Kitchen utensils are another group of things that I have found frequently suffer from abuse or loss during camping trips.  Items from a dollar store may not be restaurant quality but I find they usually at least match things I buy at grocery and department stores and, once again, the low cost makes them cheap and easy to replace when they get ruined or go missing while camping.  The low cost also means it is economical to bring along duplicates if you have room.  We've found it is often very nice to have extra spatula or serving spoon.  I've even found sturdy all stainless steel items that are perfect for camping.

There are usually a good selection of toiletries and sundries, which allows me to stock up for camping and have enough for my whole group and to share with fellow campers should the opportunity arise.  The only downside is that with the cost so low it is easy to OVER buy for my family, but at least everyone has the products they like to use.  I encourage using things like combination shampoo/conditioner or even shampoo/conditioner/body wash to minimize bathroom clutter.

Inexpensive toys for camping can be a real boon to young families.  It is also gives grandparents a way to stock up on things to entertain their grandkids during and outing or a visit.  Things like sidewalk chalk and squirt guns appeal to kids of all ages.  Same with glow sticks, necklaces, and bracelets, which are fun for after dark activities.  Even adults enjoy cooling down on a summer afternoon with a "Supersoaker" squirt gun fight.  And the dollar store lets you arm your whole army without a big price tag and the low cost pretty much eliminates worry over them getting lost or damaged, which are both frequent occurrences with any group of active youngsters.  The variety of crayons, colored pencils, and colored markers along with pads of various sizes can provide hours of entertainment for the budding artists in your group.  You can usually find a variety of simple games as well as other basic toys to keep the little ones busy.

Flashlights and batteries are always good to have in camp.  While I do enjoy using my sturdy aircraft aluminum Maglite, inexpensive plastic flashlights and LED lights from the Dollar Tree are really nice for children and as loaners.  The low cost batteries may not last as long as higher priced brand names but since they spend so much time in storage it is good not to tie up a lot of money and yet have an adequate supply of replacements for every application.  I've used small Dollar Tree LED flashlights in my tool kit on my dirt bike we great success.  They are sturdy aluminum construction, are light weight, and have endured 100s of miles of bumpy trails.  The low cost allows me to stash little flashlights wherever they might be needed for added convenience in my RV, camper, and motorcycle trailer.

Some people might be kind of choosy about tools and hardware, but low cost might allow you to supplement your tool box and spare parts with little investment and you don't have to worry about losing your good stuff.  I frequently find little items, like razor knives, that are handy to have in my camp kit.  I would not be likely to pay normal retail for them for such occasional use, but being able to have them at a reasonable price often makes many tasks around camp easier and more fun.  It also allows me to duplicate some hand tools so I can them where I frequently use them instead of having to always go back to my tool box when I need something.    An extra screwdriver and/or pair of pliers tucked into a pocket or pack can be very handy.  And they don't have to be heavy duty, precision items for occasional light use around camp or on the trail.  I've even picked up rolls of wire that is perfect for wiring hand grips on OHVs, sometimes getting 3 rolls of different colored wire for $1.00!  BTW, you'll find that a pair of specialized wire-tie or "safety wire" pliers will make that task pretty easy and kind of fun, but you probably won't find them at your dollar store.  Try your favorite OHV or auto supply store.  They can be a bit pricey.  I've seen them from $30 to $385!  One of the best deals I found was two pair (6" and 9") plus some wire on ebay for $31.99.  Wire tie pliers have a locking mechanism to hold the wire secure while twisting it with a special built in spinner as you pull on the pliers.   It will pull the wires nice and tight and lock them securely in place with a very tight, neat twist.

Having access to inexpensive products provides an opportunity to experiment with different things to find out what works best for you and what you like best.  If you get something you don't like, you've only wasted a dollar!  I've found that particularly useful for kitchen utensils.

Happy Shopping!

The Rule of Threes

The Rule of Threes is a basic concept for survival.  It applies in disaster situations and in wilderness survival situations.

Simply put, you an live 3 minutes without air, 3 hours without shelter (in an inhospitable climate), 3 days without water and 3 weeks without food.   In a disaster situation where you have victims injured by falling debris or from falling down, their injuries may have stopped their breathing.  You will need to clear their airway within 3 minutes and, if they don't start breathing on their own, begin CPR.  If you find yourself stranded in an inhospitable environment (cold and wet or very hot), you will need to see shelter or you will be likely to die with 3 hours.  If it is cold and wet you will need to find someplace warm and dry.  If it is hot you will need to seek shade and ways to remain cool.  If you are in a mild climate shelter may not be such an urgent need.  Water will be your next priority.  You can live only about 3 days without water. You will being to feel the affects of dehydration much sooner than that and will want to find water as soon as possible.  In hot weather you may not even last 3 days without water.  Most people will be able to survive about 3 weeks without food.  If you are particularly thin or have medical conditions that are sensitive to what you eat (like diabetes or hypoglycemia) you may experience difficulties much sooner.  If you have any such conditions you should take steps to ensure you always have timely access to necessary nutrition.    Your body fat reserves may affect how quickly you experience dehydration problems too.  Especially thin people may feel the effects of lack of water fasting before the end of the 3 days.  People with extra fat reserves may be able to last longer than the predicted 3 days.  While you can survive for about 3 weeks without food, you will begin to suffer the affects much sooner so it is a good idea to seek nutrition early in a survival situation.  Without food your body will begin to tap into your fat reserves and you will find  yourself low on energy and discover it is hard to think straight long before the 3 weeks is up.  Ever get a "hunger headache"?  Sometimes you only need to miss a meal or two before one strikes.

Knowing you can go three days without water doesn't mean you should.   You will begin to suffer the effects of dehydration long before that.  Not only are they unpleasant and painful, they will inhibit both your physical and mental ability to take care of yourself.  The same is true of food.  In a survival situation you will want to start finding something to eat as soon as you can.  Although you can live weeks without food, you will quickly loose strength, energy, and clear thought you need to survive.

Knowing the Rule of Threes will help you prioritize your actions an emergency situation.  Otherwise, you might react to being thirsty or hungry and spend time looking for food and water and ignore the need for shelter until it is too late.

Threes a charm!
