Several years ago I was on the shelf with a pretty gnarly leg injury that had me off my feet for several months. After PT was done I still had problems standing for more than a few minutes. I had the brilliant idea to try to get back into pinball to help with this. A friend sent me a pic of an MM at a nearby bowling alley so I started my other PT... Pinball Therapy. That helped me stand for a while. I also was able to vastly improve my game and before long I was standing in front of that game for 30-45 minutes at a crack for a single game. So, mission accomplished.
