Did you ever take note of when or what "aged" you the most? Not so much one disease or event. I'm talking slowing down, the gray hair, wrinkles, spots, joint problems etc. For me it seems to come after minor illnesses especially stomach problems-nothing major but if my stomach acts up by the end of the week I wound up with a few extra grays, wrinkles, stiffness etc And as an adult I've been rarely bed ridden with the flu, virus, colds etc. I tend to get tired rather experience the full blown symptoms of runny nose etc. It seems like what ever my body was fighting included lost battles to the effects of aging. It's seems like a medical or biological condition has caused most aging for me rather than a clock.
