Gravitational Time Dilation

It would be so cool if I could manipulate time. There are so many things you can do with that, you know? Here's a few things I would do:

- Jump out of a plane, let myself get like ten feet or so from the ground, and then rewind. I could do that all day.
- In the morning, when I wake up and feel all tired and drowsy, freeze time so I can sleep for a little while longer..
- Take a test for a class at school, wait for the results, go back in time and answer all questions correctly that time. Repeat if necessary.
- Sunday night: go back in time to when school let out Friday and enjoy the weekend again.
- Get a haircut that is totally not my style, just to see what it would look like on me. Then, of course, go back in time before getting the haircut.
- If someone was really upset with me, I'd go back in time and not do what I did that upset that someone, if possible.
- Make time go faster in yearbook class.
- Make time go faster when I'm bored.
- Go way back in time just to see how things were back then.
- Go way forward in time just to see how things are going to be.
- After eating all my candy from trick-or-treating on Halloween, I would go back in time to the moment just before I started eating it.
- Easily win the lottery by going back and buying a ticket after hearing the numbers.
- Go back in time to catch missed flights.
