I ride to forestall arthritis. Now closer to 77 than 76 I've worked part-time in a hardware store since late in 2014, often exceed 14,000 steps in a nine-hour day on a concrete floor. 50# bags of birdseed or concrete mix, 40# boxes of nuts & bolts stacked & stocked on a routine basis.

Riding uses other muscles and movements that help my body stay flexible I think; what I see around me in others around my age gives me pause for what their earlier life activities & diets have left them with. I'm quite glad I can still ride miles when weather suits, on a trainer when it doesn't. My cardiologist agrees with this.

Only major complaint now is left thumb arthritis, likely from repeated hyperextension injury over time a few years back when I was messing with tools and got caught by surprise when that thumb joint 'popped' unexpectedly.
