I'm of the gardening sort too. I really like working in my yard. I also go for rides on my motorcycle...just a quiet back country road. When I'm really over the top frustrated with anger (e.g. a run in with my ex wife) I play the most violent "first person shooter" video game I can find, or I take my rifle out to the range and put a few boxes of shells through paper targets. Believe it or not, nothing calms my nerves like target shooting. You HAVE to relax in order to be any good at it. If you are all tensed up and angry, you'll be lucky to hit the paper, let alone the X-ring.
