Absolutely. I'm into mountain biking -- lately, it's been a lot of night riding on local singletrack. One of my fellow riders said "What is it about programmers that makes them want to hurl themselves into trees in the dark?". The answer, of course, is stress. 85% of us are software developers.

I don't feel like Googling, but there are some good studies that "runner's high" (which bikers also get) might produce effects similar to marijuana smoking (aka THC). I don't do drugs, but I do bike :)

Anyhow, monitors (esp. CRT's), desk chairs, and endless telecoms don't work well for me. I have to get outside and play.

Of course, it's been raining llamas and camels (err, does the idiom "raining cats and dogs" translate well internationally? If not, sorry!)...so that makes it a bad week. Time to start hitting the indoor pools or something, I guess.

Beer helps too :) (but no I have not tried any of blue_cowdawg's "fine Belgian style ales")
