When I was drafted at 23 I was surrounded by children----most of them school drop outs or delinquints of some sort or three traffic tickets and the judge said join up or jail!!!!!
After a couple years of wasting my time ( not properly using my abilities ) I would sign up for 24 hours duty free of charge, only if they used me to the best possible means--and I don't want to be an astronaut ( I've flown with some of them already)
