Age Is Not A Diagnosis, 1
Gabrielle Marcus
Sometimes people self-diagnose their condition as "age" when what they really mean is "time". A 20-something marathon runner who gets an injury at mile 21 doesn't think, "Oy, I'm so much older than I was when I started this thing." If you've been pain-free for years and suddenly have pain, if a pain you could live with suddenly becomes too much to bear, or if your body used to recover quickly from nagging pains but starts to send out a steady alarm, you may have just reached the point in your marathon where your body is calling for rehab and changing form or lifestyle.
