I jumped out of a perfectly good airplane, once... for the
LAST time. My GF at the time was getting into it so I thought I'd try to see what she liked about it.
It was fantastic, and I'll NEVER do it again. I found out why people do it... It's for the rush.
I also stood up in front of seven or eight thousand people with just my guitar and my performing partner and his guitar and knocked down the audience with our songs. Nailing a live performance is the same rush. If you blow it in front of thousands of people, you can die just as bad as if your chute fails,
but you live to tell about it! It's a spiritual death, instead of your body, but the good thing is, you get to try again.
OTOH, there are no second chances if your chute fails. :Q You don't have to put the entirty of your physical being on the line just for a rush. There's always another one somewhere else that won't kill you if things go wrong.
