Thank you. I am hoping that this is short-lived and I can move on. And I am happy to hear you are recovering well!
My injury now is nothing on that magnitude, but I did have a motorcycle accident several years ago that was similarly severe. I was hit at a four way stop sign by a soccer mom who was on the phone. I stopped, she didn't. She hit me, I went flying into someone's home. They came out with baseball bats thinking I was trying to break in. Fortunately, it was in the winter, so the snow banks saved my head. Despite having a helmet and everything, I had several broken bones, a broken neck, and a severe concussion.
It took me ~2 years to fully recover, and tons of physiotherapy. My then girlfriend (now wife) wouldn't let me ride for a long time after that.
And much like you, I am a mess of injuries -- broken neck and vertebrae from the motorcycle accident, broken fingers, nose, and dislocated shoulders from climbing accidents, head and shoulder injuries when I hit a tree head-on snowboarding, cuts and bruises from other stupid things I have done over the years (white water rafting over a ravine, cliff jumping etc). And given the number of outdoorsy (and stupid) things I've done over the years, I have been surprisingly fortunate!
As a biker, you are probably just as conscious as I am about your VO2 max. I do a lot of high-altitude climbs as well (i.e., not just technical, but also alpinist style) and a low resting heart rate and VO2 max is very important in being a successful climber (and good pilot, although my days of flying jets at blackout-Gs are long over).
Of course, having a kid changes all that. And one of my best friends died last year on Mount Rainier in an avalanche, and that has made me reevaluate the risks I take while climbing or pursuing other activities. I may just have to resign myself to pursuing some indoor and sport climbing until such time that the little guy is old enough to join me.
