If I had the power to change the world right now, I would get rid of cancer. Find a cure that doesn't kill the patient. I won't be able to help on this... I wouldn't be able to tell Coke and Cough medicine apart if it weren't printed on the bottle.
Series, ever thought about the fact that helping the world might help yourself, too ? Or your loved ones ? Or maybe just the guy who's giving you a free ride tomorrow ?
