It felt good to turn 75 this week. My wife asked if I felt 75, and I said, no, I feel 85! Just kidding. I used to run marathons. Four of them wore out one of my knees. Twelve years ago, I had one of the knees replaced. With Fitbit and my Apple watch I have counted steps on the new knee, currently 32 million. No running, just walking. Yesterday, I walked 3.1 miles, and in the hills of Pennsylvania, it was quite a workout for me. A friend of mine in Florida reminds me the key to health is to “keep moving”. I’ll do my best.
