Getting Old

So, in a fit of drunken Wrestlemania stuntliness over the holidays, I may have strained-cum-torn my MCLs. The X Factor was my 260 pound little brother. Landing on top of me. Think lifting wrongly but injuring your knees, not your back. Good times. I'm supposed to go to an orthopedist next week. In the meantime, I'm feeling old, slow to heal and beaten. And in pain. A new pain that I'm not familiar with so it's hard to accept. I get old pain; I can handle that. This is new and it sucks. What's next? My hips? Perhaps I should buy a walker now...
