My son made me go bicycling this morning with him, with the heat already rising.

3. Thanks. Believe me, I'm well aware of the danger of this heat.

I told him we had to get out early to do it. It would be impossible to do it now. It's already 93F, and I'd suspect it will hit 100.

We only went about 5 miles, round trip, mild hills.

It sounds as if you're aging backwards, by the way. There's certainly a reason you have had the pleasure of living so long.

In my 30's, my wife used to run for an hour, sometimes more, on the beach. Neither my knees nor my hip would take that now, but the bicycle is a different story. It strengthens those parts that hurt now.

I've never really managed to have an exercise routine indoors, with the possible exception of doing push ups and sit ups in my twenties.

I was big into bicycling in my 20's. There was a part of my time in California where I got rid of my car and biked everywhere, between 50 and 100 miles a day.

As you're even older than me, let me share my favorite thought about aging other than the one I tell my wife to the point that she now rolls her eyes, ("the alternative to growing old is dying young):

"Growing old is like climbing a mountain. Your breath gets shorter but your views become more expansive."

I believe it's attributed to Ingmar Bergman.

I feel that very much. I have never before been so aware of how beautiful life is, now that most of it is over.
