I had a similar experience after walking out of my last consultation before my surgery. It was the consultation where the docs laid it all out and it really hit hard. I was walking down the street in a bit of a daze thinking about the massive changes ahead, when i looked across the road to see a guy "walking" down the road with no legs. He had prostheses on both legs and seemed to be doing fine.

It was good timing for me - reminded me that life is full of crazy challenges, and sometimes you get one without asking for it...
