I would travel to Greece, Rome, Malta, Tunis, and Egypt. One day in each, with my family of course. Those are the main places I want to visit before I die.
Ask the girl I love if she'd like to spend the 5 days with me. If not, travel to space to look at earth from space. Some say it's a staggering, shattering experience. I want to know how it feels before I die.
Take a road trip, have a rave, go to some concerts, travel to space and, as I am dieing, say something profound that only makes sense to me. I like bothering people because most will try to make sense out of even pointless chatter. So, I will be happy to die knowing that that person will be bothered by my final words for the rest of their life and they will hopefully pass it on.
I'd do every random thing I ever had the slightest desire to.. Running down the streets screaming bloody aliens and stuff like that. And of course I'd do the things I'd never get to do, at my age I would drink till I was drunker than a doornail. And I'd get my will together, tell my family I loved them, and as I lay dying I would say, "This is not the end"
I would cry because I keep dying in Runescape on my 5 day marathon of continuous gaming. Then I would go to the shop, buy a shotgun, return to my mothers basement, and shoot my computer to bits. Then moments later I would die, because I can't live without Runescape.
