Based on his terrific books his occasional appearances on Radiolab, Oliver Sacks seems like a really great guy: smart, funny, and curious. So it's pretty sad to hear that he's been dealt one last shitty hand. But at the same time, it sounds like he's totally at peace with it:
It is up to me now to choose how to live out the months that remain to me. I have to live in the richest, deepest, most productive way I can.
He'll be missed.
