Some cacti will make you vomit if you eat the pulp or moisture it contains. Others will give you diarrhea. But getting past the darn spines will drive you crazy, anyway.

Moss grows where there is moisture and shade. A cluster of trees provides a lot of shade, and low branches provide shade, so moss grows all around the trunk. A single tree with limbs high enough to expose the trunk to the sun will usually have moss on it's north side. But not all growth on a trunk is really moss. It's good to know your mosses.

Sure, it's the calories that heat the stove, but if you're verging on hypothermia, do you really want Hagen Das? And I thought the doctor's example of dumping a quart (or whatever) of hot water into a larger amount of cold water was kind of stupid. You're pouring a cup or two of hot water into a bag the size of your fist (or two). It's going to stay there for a bit, then gradually flow into your small intestine. And it's going to cool down more slowly than his example.


If your feet or hands or other body part is cold, cover up whatever part is exposed. It doesn't matter how much body heat is lost through the head... in a cold situation, ANY is too much.
