So Ive been playing alot of AoE DS recently, and I though "Hey, all this laziness can't be good for me at all!". So, I read in a post on Gamespot that some guy saw a kid playing his DS on the treadmill, which gave me the idea of playing AoE and walking on the treadmill at the same time. So, I went and picked up my DS, made sure AoE was in it, and stepped on the treadmill. In 30 minutes I burned 203 calories and played 2 games of AoE! The best part is, it felt like 10 minutes! I think I'm going to keep this up!
