Hmm...lets see, I've already been skydiving, so that's out. I race motorcycles and climb mountains on a regular basis, and I've flown an airplane before, albeit breifly... but there are a couple things I do want to do yet. Travel to another country...not really sure which, maybe Japan, Australia or maybe a couple places in Europe. Become an amateur/semi pro bodybuilder or maybe UFC fighter. Get good enough at art to either create or help create something awesome, like a comic book, anime, cartoon, etc. That's all I can really think of right now. P.S. - Anyone who said they'd like to go skydiving, just go. Seriously, go on your birthday or something. It's typically about $200 in the US and it's nowhere near as scary as you think it might be, and statistically speaking it's very safe. It's pretty awesome, but not really that big a deal where it should be reserved to your bucket list. Besides, extreme sports is best enjoyed while you're young, if you wait til you're 80 you'll prolly have a heart attack before you even jump xD
Scratch what I said earlier. All I want to do before I die is play Grand Theft Auto V. Maybe I can get them to send me the game through the Make A Wish Foundation if I were terminally ill :/ Excuse me while I go get bit by a Black Mamba
