My gym and hiking buddy commented a few years ago, "Gawd, I hope I'm in HIS condition when I'm his age..."
His teen-age, wise-guy son answered, "Heck, you should wish you were in HIS condition when you're you're your own age age now."
...Which tell you more about teen-age kids than it does about conditioning.
But I am pleased to mention that although my ol' gym buddy is no longer lifting, he has taken up long-distance bicycling, and is keeping himself in damn good shape.
I owe him a debt for calling me back into the lifting sport several years ago.
