I didn't see brokeback so don't know those guys.
mimi, you have to work on endurance, eat well and be motivated to do those things tennis players do.
You also have some good practitioners of Tai Chi and Chi Kung (qigong) in China.
Both of those can help a great deal and start out easy.
Start moving your body!
Jake also acted in "Prince of Persia" and "Source Code", and you still don't know him?
Tai Chi and Chi Kung look very slow and boring ........
Yes, i need to move more my body after eating so many moon cakes. I will start by cleaning the dust in my boss's room.
