I am 64 now so I cannot remember all the foolish things I have done but here are a few I can remember.
1. Never share a fighting hole with anyone braver than me.
2.Never scuba dive at night in shark infested waters.
3.Never argue with a woman
4.Stay at least 100 miles away from my ex wife,{see # 2.}
5.Never light a fuse that has a burning rate faster than my ability to clear the area.

Tequila and I came to an understanding several years ago. I leave it alone and it leaves me alone.  That stuff is evil.

Take myself too seriously..

Nice answer John ;-)  I used to save (for a riany day perhaps?). Nowadays life is so expensive I don't have the spare cash to put away ;-(
Means I'm waiting for a lump sum pension payment from a previous employer to pay for my intended 50th birthday trip (and possible custom order) to the mothership.

p.s. the other thing I don't do now is slide down the side of the local pit-heap (mining spoil heap) on a tea tray ;-)

Ride my motorcycle when I'm hammered.

I disapear and I stumble on this thread!!! :rofl See Flax's above comment!
 
There is not a whole lot I have ever done that I wouldn't do again once in awhile, and I do since I still travel and see a lot of music... Though if I had to pick one it would be picking fights with people much bigger than me.. :shakeing head for long lost stupidity
