Shamus, I'm glad you made that post 'cause it gives me a better idea of what I'm facing, and how long it will take. (I fell 25 feet out of a tree in '98. One of the things that happened was my pelvis on the right side was torn completely off the spine. Now it's bolted back on. And I got a crushed L4 vertebra. I'll stop the list right there) And I've been wondering how long it would take for me to get back in some sort of reasonable shape.
I felt like I was about 35 when I went up that extension ladder (I was 53) and when I hit the ground I felt like I was 80. It's been a slooooooooow recovery. Now I feel like I'm about 69 (I'm 58), and I've not felt like myself ever since that day. Any way, maybe 8 years and I'll be about where you are, recovery wise.
Thanks,
francois
