Hypotheitically, if you could freeze time, and move freely while everything else around you was frozen in time, would you age or age very gradually?
This is a fantasy thing, so nobody can give you a "right" answer, however, if you are developing a science-fiction plot the lazy way, here's my take: If you could "move around freely" then time would not be "frozen" for you, only for everybody else, and you would age at the rate of one hour per hour of your subjective time. So best not to do it for too long, because you would seem to get older awfully fast in the eyes of everybody else. They'd probably think you had some terminal disease. By the way, that's not how you spell "hypothetically".
