If your leg is in a cast, it's really dumb to sit in front of your computer doing unnecessary stuff with it hanging down. Your leg will swell and heal slower, if at all. When you go to your doctor, he/she will give you one of those "you're really dumb and self destructive" looks. Also, "Why didn't you follow my orders and rest?" Your doctor will be right, and so will mine at my next office visit. Elevate, folk! Elevate your mind, your soul, and your leg, in the order needed!
