Sure i'd do it. Im over 30 now so being 16 again would be great. I wouldn't have to worry about various crap like bills, food, annoying bosses and could just have a good time without any responsibilities. I could even go out for a party and come back after 3 days and it wouldn't be a big deal at all. Give please, but i wouldn't do anything differently than i did last time i was 16. Im proud of every 'wasted' opportunity and of every 'bad' decision i made.
