1) To be able to turn back time and erase all the stupid things I've ever said to people that caused me embarassment or regret.
2) To be financially secure for the rest of my life, nay, sod that actually, I want to be rich.
3) Invincible, so much so that I am able to comically walk out in front of cars and be hit, scaring the wits out of the driver and hopefully causing them to never want to drive again and then be able to get up, snap my broken bones back together, seal over my cuts blow my bruises and watch them disappear then walk away beaming with pride like a hero of the highest order.
