One thing that is hasn't been mentioned on the site is the power of positive thinking. You could be perfectly set up for a survival situation but end up dead if you have a pessimistic attitude. Where as a positive person could be given next to nothing but still survive for as long as it takes to get rescued. It's an interesting subject and it makes you wonder how many people have died needlessly because of negative thoughts. As Oddball out of Kelly's Heroes might say, "Knock it off with the negative waves."
