Prepare for inevitable
When a man gets in an extreme situation he starts to panic, be it a car-accident, an airplane crash or getting lost in the woods or in a dessert – first few minutes determine it all, because the man has to make the right decision. Usually these are the minutes of panic. But if you were to wait for help, you have to settle yourself, make a shelter and wait, because if you go you will die. Or the opposite – you must move on, because if you stay, you will not survive, as in a situation a man stayed in his tent instead of going a couple tens of kilometers and died of bad water.
