staying in shape for survival
There were at least 2 occasions here where physical conditioning helped me to stay alive. Once during forest fire when I had to run a considerable ways to escape, and once in a flood where I had to quickly move to high ground through dense brush. Also, though it is not such a life threatening situation for me, I had to carry injured person a considerable distance out of jungle before he was packed out on elephant. The point is that besides all the various items and knowledge one needs in a survival situation, your own body should be as dependable as your equipment. Some people stay in good enough shape through hiking and other outdoors activities. But for those people who do not, it is important to stay in shape through some regular exercise program.
