This old ranger volunteered before and would do it again if they'd have me. I don't suppose they'd let me still jump out of perfectly good airplanes, though. Still sounds like fun...
Former Pres Bush Sr jumped recently! He chuted! :)
I'm 62, ex-Special Forces, veteran, but I would go back in a second. I would no doubt be a liability in combat, but I sure as hell could train some of the youngsters.
