Pratchett was on to something with the entire Discworld and other stuff besides.

Every time I hear of a new, promising cure for Alzheimer's I go a little happy and a little sad, because I think that, if he had held a bit longer, maybe...

But then, none of those cures ever work out in the end so I'm just left with the sad. Sad that I never got the chance to see him up close and shake him by the hand.

Thanks for introducing me to Terry Pratchett!
