Wow....that is crazy! Glad you pulled through for sure. I too was in an accident that almost killed me. I ended up with a broken neck and had a frontal brain injury. Does not sound as bad as what you have to deal with cause on the outside, I did not look as if anything happened.
The gym, and thought of being able to return, really helped me. Good luck, I know it must be hard to have to plan ahead for surgeries. Best of luck
