I’m absolutely sure that if I’m lost in the wilderness I won’t survive enough to get someone to find me. I’m completely adapted to living in cities and I prefer to continue watching the wilderness, deep forests or similars on TV.
In fact, I’ve never needed making fire in a situation like this (in the forest, mountains or desert) but if I would be in this, I would use some tinder and a piece of glass to warm as much as possible the tinder and with a lot of patience and sweet blowing I would try to get some flames.
In case of this emergencies, the first thing that I do would be getting a safety place to rest and protect myself looking for open spaces to draw attention of anyone who could see my signals. I would look for some water and, if the situation lasts too much, I should try to find something to eat, too. In this case and attending to the cirumstances, I would become vegetarian.
