Well, that depends on what you want to do. Have you ever been to europe? There are some cool things to do abroad (<-double entendre), one thing I'd like to do would be to go back to germany. I heard there is a car rental place that rents out fast cars for a reasonable price for the day to drive on the autobahn.
Are you in decent shape? You could backpack around europe, see a lot of things and have a chance with a lot of different women from different cultural backgrounds
You could just simply make a list of 100 or so things that you want to do before you die. Then spend the next however long knocking them out one by one. Have you ever: went sky diving, slept with a red head, attended a ufc event, maybe brew your own beer?
good luck man
