if you could turn back time

what would you do if you could manipulate time?
things i would do if i could control time.

1.spend more time with my family
-it'll probably prevent certain things from happening.

2.spend more time with friends
-its essential for keeping them

3.stay 16 FOREVER :)
its sweet sixteen afterall

maybe i should go into the future and get the ultimate cure for cancer! then come back to our current time to be a multimillionaire!haha
