Years ago I had a co-worker who was diagnosed with lung cancer. He was terminal.
He alway rode an old custom bike, I think from the 60's, and always dreamed of buying a brand new Harley. His wife talked him into buying his dream bike while he could still ride.
I was sitting in the parking lot early Monday morning waiting for him to show up and open the gate. He pulls up to the gate on a brand new Harley. Stops. Doesn't put his feet down. Him and the bike fall over like timber.
I assumed his lace got caught on the gear shifter and ask him if that's what happened. He looked me straight in the eye, and with a straight face said, "No, I just forgot to put my foot down." That's one of the best laughs I've ever had! He swore it had nothing to do with his condition and was just a brain fart.
The only damage, if I remember right, was a broken clutch leaver. Snapped about 2 inches off.
Unfortunately, he passed away less than a month later. Cancer can move real fast when it wants to.
