There may be some sound medical findings behind your actions Rail' and CK's playing of the Tropico CD's may confirm this.
Sitting at your PC, music-a-playing the urge to tap the foot, thus aiding the circulation.

Recent studies (which I, as a person who does little exercise grasped on to) is that simply thinking about exercise and using the mind to go through the exact actions of a particular exercise can provide strengthened muscle mass.
Therefore you may now all picture me sitting at my PC, thinking about bulging biceps and butt-cheek curls.
Throw in an AAR and that is one cool exercise regime.
