Well, I am pretty sure I qualify for this thread because I am 73 and just bought a Trek 7.4fx two weeks ago. Haven't ridden any distance except a 10 mile ride in Germany three years ago. So now I am riding a little every day in our neighborhood...2+ miles...and it is beginning to feel good. Our neighborhood is very hilly, so i get to use all the low gears for sure. My hands were going numb, so I had a stem extension installed and that has helped a lot with an 80% improvement. Today I bought some gloves with the tricky little pads, so I am hoping that does the rest of the improvement.

I have been a regular gym go-er for the last six or seven years, and before that I was a runner...long distances and very slow. So while I have some aerobic base, my body is still getting used to this new activity. I have a lot to learn.

I am happy to find this thread, because I thought I was the only 70+ year old riding...but now I know there are other strange people out there like me.
