So, what do you get out of your run?

I wasn't always a SIXTY-FIVE-year-old runner. THAT sounds old to me...who is 65. Maybe that's one thing about running and one reason I write here. I feel the same as I did at 20 but I worry about my weight less. I wear a size 2. At twenty I wore a size...7 or 8. The thing is, I'm 5'2" so a size 2 works better than the size 7 did. Or...did I wear a size 1o? Oh well, happily, I don't remember.
