I've found that hacking on my house provides a lot of needed physical labor/activity.

I do things like improve the lighting in my garage so I can work on various projects out there. I'm also thinking about taking up gardening.

I too have really felt the urge to get up and do real physical stuff lately. I wonder if it's part of the disillusionment of web 2.0. So much bad news about the economy,etc that I don't feel that working on the "next big website" is really going to pay off.
