What type of hobbies do you have?

[egoldstein]

I have a number of hobbies, some would probably say I have more hobbies than sense.
I'm an odd collection of hobbies, astronomy is a perenial favorite, both viewing and telescope making. I loosely follow paleontology, botany, and entomology, plus a fair bit of behavioral science. I like working on mechanical and hydraulic systems, computers and networking, gardening, and studying philosophy. It's hard predicting what will grab my interest next.
