For some reason, I just now noticed this thread, probably because it is a "sticky" and I almost never look at those. Anyway, I'm 70 and have only been riding for about 7 years this time around. I rode when I was a kid, of course, and even ran a 14-mile paper route on a heavy old J.C. Higgins Flightliner back then. Broke the frame on that one twice; also broke a late '60s Huffy. In the late '70s, I bought a nice new Nishiki 10-speed with the plans of riding it to work at GM. Thought I was going to get run over! That turned out to not be a good idea in that traffic!
Back to now, I laid off riding last year because my wife/riding partner was having some irritating health issues and wasn't comfortable riding anymore. In the process, I gained back about 10 pounds I had lost a couple years before and I missed the riding. I love riding and I love bicycles. I collect/buy/sell old bikes, too. Before last year, I was doing pretty well, averaging around 10-12 miles a day. On my 67th birthday, I had a goal of riding 37 miles. I did 42. Then the next year, I developed a-fib, so that slowed me down some. I'll be on blood thinners the rest of my life, but thankfully the ol' heart is staying in rhythm and I feel good. As soon as the weather warms up just a tad more, I'm ready to get back at it.
