Man, that was tough to watch. It was amazing how much of a stark contrast his emotions came across -- he was quite positive, yet you could tell his extreme dejection knowing his ultimate fate.
Even not knowing him or having heard him before, you could tell the effect it has had on his speech, both in terms of the slowness and slight hoarseness in his voice.
It's an absolutely horrible and devastating disease, and I wish him all the best in his toughest battle and hope he is able to do what he loves to do best for as long as he can.
