Are you physically prepared to survive? I went skydiving last weekend too prepare for the coming doom and realized at 57 I am not in the shape I should be for skydiving or more importantly surviving. Can I walk 5 miles to fill a bucket of water and then carry it back? Can I work in the field all day tending my crops? Can I work all day and go hunting in the evening and bring the game home? I have increased my daily exercise program mostly for future skydiving (tomorrow) and hopefully not for survival. Without proper conditioning I realized that even the smallest injury could keep from performing simple tasks. The only way to reduce these types of injuries is to stay fit. In the process I feel better and have more energy. Making sure that I am physically prepared to take on whatever challenge is thrown at me will not guarantee that I will be free from injury, but could be the determining factor in surviving the landing while skydiving or surviving the crash of this economy and the USA as we once new it.
