Noelle: I pulled a hamstring the other day while sitting down.
Jessica: I'm in serious pain, had to take a cleaning time-out.
On a related note, you know you're getting old when all of your friends who signed up to run a marathon this year had to drop out after suffering some kind of body ailment during training. See this is why I don't bother doing things anymore. You spend five months getting up at 7 a.m. every weekend to go on some painfully long run only to be sidelined at the last minute by a stress fracture. I also don't trust any form of "exercise" that comes with a high probability of my toenails falling out and me spontaneously crapping my pants. That is my line in the sand.
