What would you do if you could freeze time?

If I could freeze time, I think I'd try to use it for some sort of positive purpose. Would I still be able to move while time was frozen for everyone else?

If so, I'd go to war zones and find innocent people that are scared and in-danger, and move them to somewhere safer.

The same goes for people who are about to have imminent accidents. I could travel the world looking for situations I could intervene in and try to make a difference while people are all frozen in place.

I would also go see my favorite soccer team play, then freeze everything and have a walk around the soccer pitch and kick the ball about, just to see what it's like to play soccer in front of thousands of people.

I'd use it for cheap tricks - practical jokes.
