It is quickly becoming clear to me that gravity is definitely stronger now than when I was in my twenties. 15 push ups come along and I am looking at the ground like it's a nice soft bed to take a nap on. So it must be stronger gravity, it sure as heck know it's not me. There's an old saying about looking ahead to see when we are done. When you see the light at the end of the tunnel, make sure it's not a train. As I have discovered in my more uncomfortable years, it's best to live one minute at a time. Looking ahead can cause discouragement or despair. Live moment by moment, and enjoy the ride.
