To name a small few:

- I'd try to keep myself as physically and mentally sharp as I can, while still being willing to consume a good share of alcohol, sweets, and greasy food.
- I'd have sex with as many attractive women as possible, and produce a few children to see if they can accept the challenge to try and outlive me.
- I'd take trips back and forth to other planets, whether it's Mars or it's an artificial man-made planet constructed by brilliant scientists.

Obviously I'd hire a 20 year old hooker.

In that age you would probably get a heart attack with 250 years younger prostitute, but at least you would die like you have lived..

Hilariously good point, Janina!
