Awesome video, even if you busted your foot. I regret having come from a family where Dad would not allow any gasoline engines in the garage (except the car). I had friends with mini-bikes, lots of Briggs-n-Stratton and Tecumseh lawn mower engines got repurposed back in the 70s. LOL I'm glad to see that you have the spirit to enjoy life. 59 myself, I started a running career at 52 and ended it at 57. Was fun, but knees don't reproduce new cartilage.

Was fun to be competitive though. I guess that's a human trait - we all love winning. :)

And yes - MAGA! WWG1WGA!!!

Stem Cells for Knees: Promising Treatment or Hoax?

I haven't looked into this treatment, since my knees are still working fine, but it's something that appeared on my radar recently. It's a treatment that may offer an alternative to knee replacement surgery.

Do bicycling. If you want pain, try the 2014 Tour De France, where Mark Cavendish crashed with another rider during a sprint and dislocated his collarbone, and two weeks later, Alberto Contador crashed on wet roads, got up, and biked 20 more kilometers including 10 or so uphill before abandoning the race with a broken *tibia*!
