His comment was not meant to be profound but it was…at least to me.
He is a top athlete. He trains all the time getting ready for some iron man event some place.
He commented that he knew I was working out at Crossfit. He commented on the effort being made. Then he said that what was really nice to see was that I wasn't doing it to get ready for some contest but rather I was doing it just to do it and be in the total mix of life each day.
Doing it to just do it. No other purpose.That duality thing again.
Be your life. 
Be all you can be just so you can be all you can be.
An ageless experiment.
