Time. At least I'm not alone in that scenario. Besides, you never know what kind of stuff you'll learn from the past/future.
WYR be at school in only undergarments in front of everyone you know, or run naked through a school you've never been to? (note: for the purposes of this question, there are no dress code penalties for either instance)
Never be able to drive. Taking away my ability to play games is taking away 70% of my life. Besides, I live within walking distance of most places that I visit on a regular basis.
WYR... Have no friends, and no enemies, or have an equal number friends and enemies? (the intensity of the relationships also matter- if you're very close to someone, you'll have an enemy that hates you as much as that person likes you, etc.)
Wonderful friends and fearsome enemies. I have a feeling that I would have a few super villians as enemies, as I tend to form strong bonds with my friends. Plus I'm a jerk and love aggravating people who hate me.
