I’ve noticed that in Alaska, before they leave their cabins for the day, thoughtful wilderness dwellers lay a fire in their stoves so that if they come stumbling back, frozen half to death, they will not have to build one. All they have to do is strike a match. I once watched a friend of mine who was in the early stages of Parkinson’s Disease try to make a fire with bone-dry tinder, kindling, and wood, and be unable to do it. His shaking hand put out the matches when he tried to touch off the tinder. If you are shaking from cold instead of Parkinson’s the result will be the same.
