There is a 'classic' survival book called HOW TO STAY ALIVE IN THE WOODS by Bradford Angier.It is classic, as an example of fossilised, often erroneous and untested information. Angier merely collected anecdotal information from many sources. Outdoor Life is 'doing an Angier' here. Somebody on their staff will pick up a paycheck friday. Somebody somewhere may get lost Friday and die from misinformation. You DON'T drink unfiltered urine. If your in tropical climes you CAN use ants as sutures, hopefully not from OUTDOOR LIFE papercuts.
