physical activity

i can't tell you how much physical activity means to me for somebody that was at one point recommended riddalin. when i used to get hyper active as a kid my mom woudl make me run around the block. today, i've been studying inside all day, and i just went for a quick bike ride at as fast as i could go. and it cleared my mind. it was like i was a pot of water that almost boiled over, but i needed to give myself that extra push to boil over and then come back down to earth and normal brain functions. thank god for bicycles.
