Photography, cars, guns. Car photography mostly. Also have a motorcycle, but that's a different story... Ex roommate fucked me over on that one and stole my carbs.
I restore houses that appear to be degrading. I also fix broken cement, and brick walls that are falling apart. Another thing I do besides computing is mentor people on how to manage money, and set priorities. For Example, I would mentor someone and help then with a budget to renovate where they live before they spend money on a activities for fun.
