Matter of choice

I´ve used to jog. But my ankles are in pain.
I´ve used to bike. But my knees are in pain.
I´ve used to play squash. But my backside is in pain.
I´ve used to parachute. But I feel real fear in the airplane.
I´ve used to have a sex. But I have no opponent for this game.
What to do?

I decided never stop my activities :)
