I'm asking this just for curiosity: Imagine your are alone in the wilderness without any resources since a few days. You're dehydrated and you find a bottle of an alcoholic liquor in your baggage. Should you drink it?
Alcohol gives you a bit more time to find rescue instead of dying immediatly. But from a long term perspective alcohol is a bad drink, since it requires a lot of water to degrade the alcohol. Another side effect is that you're drunk and could lead you to a deadly decision.
