I had to go to the doctor today to get my allergy prescription refilled (I use this nose spray every year from February thru June but I can't get it refilled w/o going to a doctor - and you wonder why health care is expensive).
Wanting to justify our time, she (actually a P.A.), after noting how rarely they see me (basically only for this one purpose) asked me a bunch of questions about my health, all of which I recognized from my reading as related to stuff that tends to crop up in people of my chronological persuasion, all of which I answered in the negative.
After awhile, and after looking at my charts and the numbers from my last blood tests a few years ago ("these are all really good numbers") she started looking at me with a look that either said, "Are you telling me the truth?" or "Are you some kind of genetic freak?"
Actually I have my dad's body- same height, shoe size, age-adjusted weight (up to age 42 when I started running), etc. He even has acid reflux problems which plagued me also before I started running. His health status, now and at age 53, is a different story.
I told her about my exercise habits and she said, "oh" in a way that implied she understood but was surprised that there are people who actually do that.
I relate this story, not to brag (he lies brazenly) but to motivate.
Exercise really does make a difference. Not just in how long you live, but more importantly in how well you live.
