I read mention of your excursion close to the Twilight Zone as bones healed this winter & spring, am glad you is still amongst us, & I am robustly unanimous in that, sir. Things happening at 30+ mph includes momentary excitement. I got to enjoy most of December in hospital & rehab after a hit & run truck nailed me at 30 to 40. Bless God, I'm not a vegetable on a hose. Relearning to walk using aftermarket parts was not listed in my travel itinerary. When I can drag my recumbent bike out, exercise will progress. Soon after that, I'll be pedaling uprights again, too. Do you still clank when you walk? Sudden impact was only 2 (yup, two) weeks after I finally started wearing a helmet.
