Said this in the counterpart superpowers thread, you would age faster as time is stopped for everyone but you. That said, probably just walk around and explore in and around town, I always wanted to see what's behind those "employees only" doors. I would also go see what people are doing at the moment I froze time, that would be cool. Oh, or freeze time during a thunderstorm, or a flurry, or a forest fire (two cities just burned to the ground in and around here, so that is actually possible)! Or some other climatic event, like an earthquake, it would be so cool to see the earth be all liquid-y.
Many, MANY political targets would be killed. Travel to places in an instant. Become a master in any subject.
However, unbeknownst to Che, I also possessed this power, and I set out, determined to stop him. A rivalry was sparked and we battled across the whole of time and space.
Why would you age faster? Surely if you stopped time you would stop aging whilst it has been stopped?
Well you would age if you could move when you stopped time. Your cells would continue to multiply and die and your heart would continue to beat.
You only stopped time for everything else, you cannot stop time for yourself because that would make you unable to move.
I have often wondered if time can be stopped. It could be alien races on the other side of the Universe can stop time and do so regularly. In the time it has taken me to write this post it is possible time has been stopped for centuries/millennia by others. Would be a cool way to travel across space. Pause time, travel for what seems like a thousand years, reach destination, unpause, appear to travel instantly. A bit like that Stephen King story: The Jaunt.
