@booksmusicanimeI'd like the adventure too. I think my biggest problem would be dealing with my greatest fear... forgetting something I've known before. And with time-travel, that becomes a little tricky. Especially since he erases people from existence quiet often. Oh, and almost all of his companions end up dying. Oh, and he probably would say no to a male companion, who can't run for more than thirty seconds. lol.
Ugh, we need to stop talking about the Doctor. It's making me want to start my Doctor Who RP... but I don't have the time to keep up with it. (It involves a plot, where The Doctor gets erased from time, and our heros have to all go and find him (All of his past selves!)
EDIT: Oh, and that's not to mention leaving everyone I know behind. There'd be no way I couldn't lie to them about it... and there's no way I could tell them all about it, and have them all tag along. The Tardis would then become a party boat, rather than a time and space machine. lol
