I was outside with my grandsons at their house. My oldest grandson is 11 and the youngest is 6.  For whatever reason, we got running which led into a race.  I had no doubt that I would be able to outrun them.  I’m in “good” shape.  I ride my 12 speed bike several days a week on my Indoor Bike Trainer Exercise Stand … thingy.  I’ll show them what a 63 year old young guy can do.
