An old thread, but I would have to go with invincibility. I would still age, and that would be the only way I would die.
-The thought of living forever scares the bejesus out of me.
-I don't really want to read minds because...I don't really care what other people think. Haha, am I a bad person? "Read what I'm thinking? How's this, I'm about to kill you, and there's nothing you can do to stop me because I'm invincible."
-Super strength would be nice too, but if I'm invincible, I could just build up my muscles and bash myself into stuff to break it.
-Flying would be quite awesome, but very hard to keep a secret if you wanted to continue with your normal life.
Whew...long post, but I love this question.
