Alright, take a moment and imagine with me, you have been a “Survivalist” for a couple of years. Every paycheck you try to set aside a few dollars to put towards emergency supplies. Thanks to your frugality and foresight you have been able to stock enough supplies to last you for some time.
As Neil DeGrasse Tyson, PhD, points out in his many videos, the earth is NOT your friend. Dropped down naked in almost any spot on earth you will survive less than 48 hours. Accept that as a fact and then proceed to make sure you are never without the tools needed to survive.
