There's a saying that life isn't about finishing in a well-preserved body. Rather, the smart way is to go skidding into the grave sideways, thoroughly worn out and finishing with the thought, "wow, what a ride!"
That's a wise view. When we were at my alma mater for my 25-year reunion (and where did those years go?!) a few weeks ago, our last event was a lovely brunch on Sunday morning. We sat with two older couples. They were from the class of 1958, so 55 years past their graduation.
These people were busy, engaged in current events, active (they were talking about going kayaking) and seemed to be living life to the fullest. They really were inspiring. No one can say how long anybody's stay here on Earth will last, but these people were a reminder that age is just a number. If you have good health, then the rest is up to you. Live your life! Enjoy the days you have, and at the end skid in sideways, exhausted and marveling at what a ride you had!
