I was paralyzed from the neck down. I will never turn my head again. I ride 1500 miles a month. Ask me about surviving hell.
I shattered my C2 (with TAL disruption, basically an internal decapitation; think Christopher Reeve but slightly worse) in a bicycle crash in 2011. I was lucky, and the paralysis was temporary, but the surgery that saved my life left me unable to use any of the vertebrae that allow you to turn your head.
I do yoga 2-4 times a week, gym 2-3, and I ride 1500 miles a month (yes, I have a problem).
I was lucky. Anyone who is actually paralyzed in any lasting way has a vastly harder life than me. I'm only slightly disabled now. But I can tell you what it's like to go from quad to jacked in 2 years, and I know something about perserverence.
edit: Oh yeah. Proof: https://whatimg.com/i/fAYodV.jpg That's what it looks like when they put 1lb of titanium in your spinal column.
