Know what you all mean. I was 30 before I realized my Dad's advice all those years, most of which I ignored, was smack on the button. About then I realized he was a whole lot smarter than I thought when I was in my teens. Both of my sons are pushing 40 and have, I hope, come to some similar conclusion. Still, I'd trade most of those acquired "smarts" for a body that didn't ache every morning 'til I get moving and for the ability to run up steps 3 at a time again.
