Apparently 31 is the tipping point into old age

On Tuesday I was sitting at my desk and stretched my back. BIG mistake. I don't know what I did but something popped and it hurts like hell. I'm slowly regaining range of movement so for right now the doctor has said heat, rest, and drugs for now (fun prescription drugs). If it's not better by Monday I'll have to go back for some tests. Who knew that stretching could do you in? Luckily I've heard other stories about people throwing out their back doing the dishes or yawning or sneezing so I'm not the only idiot around.
