I am indeed old. I don't really feel old, usually, nor do I often think of myself as old. My body at times reminds me.
Whilst on the cruise, I was idly musing about how many men were there about my age and what percentage of them could play baseball, even at my own rather ... low level. I can run the bases (aside from muscle pulls at times), I can pitch, play 1B, stumble around in the outfield if needed. The answer was not many.
Baseball is my motivation.
