I don't do much tennis these days, but everything else is fun.  ^_^

I like playing tennis, volleyball sports wise. I do however play lots of different intramural sports at my university.
I like listening to music and playing video games of course. I guess checking this site like it is an addiction counts as a hobby as well.
Cooking I also enjoy but cooking for one person is a bummer while my brother/roommate is studying abroad in Denmark.
I can't forget working out at the gym, thanks sherlock I totally forgot about that. =D

Masturbating furiously.

Oh, and decapitating people and burying their heads under my house and storing their eyeballs in a jar in my dresser drawer. That's fun, too.

 Those are some very health hobbies to have.
