I forgot to mention that survivorman is off the hook, but in a real world/life situation it would be much different. They are at LEAST giving him something to work with (a couple of matches, some jerky, a knife), but who is to say you will have these things in a real life situation? But, on the real, I think everyone here should at least look into a couple of books (dealing with survival) and really ponder the possibility that you may be faced with harsh times.
Also, do any of you have "kits" or emergency packs? I'm not just talking first aid kits, I'm talking kits that have bottle watered, matches, a compass, a knife (or a small pistol), a poncho (for the rain), etc.
