Good post, always interesting to find out what people are about aside from the pursuit of carnal pleasures...
Sports- kind of hard to call this a "hobby" considering that I haven't taken place in a competitive athletic contest in nearly 20 years, but I guess being a sports fan is kind of a hobby. I like baseball, football, basketball, hockey, and soccer, and I've coached high school football for 15 years.
Reading- I love to read, I try to read at least 10 books a year. I have a degree in History so the books I read are almost exclusively from the History section, with my main interests being Modern European History and American (Colonial, Revolutionary War, Civil War/Reconstruction especially).
Cats- I'm a cat owner (2), or parent, or I'm owned by 2 cats, depending on how you look at it.
TV- I tend to watch a decent amount of TV. I particularly like crime shows like the kind on Investigation Discovery, and I'm a huge Law & Order fan.
Travel- can't really call it a hobby because I haven't done much of it, but given more leisure time and money, I'd like to do more of it.
