Dang. I LIKED Zezel. RIP fella.
Grim:
"Hemolytic anemia" is rare depending on how you define it - the entire group of diseases isn't THAT rare, but specific types are. Just to give you an idea of what I mean: it's one thing to say "professional hockey player", as there's a helluvalot of them. You narrow the field considerably when you say "NHL player for the Pens". They're really skimping on a LOT of details, and necessarily so, given that this is a human interest piece rather than a scholarly report. Still, even saying what particular disease he had would have been good, in the sense that any charities thus devoted might have been able to reap some donations in his name.
And before someone says it: Yes, I'm suggesting that it's a good thing for a charity to be able to capitalize on a high-profile victim. There's precious little enough money going into basic research in the first place, let alone a lesser-profile disease like this one. If the passing of a well-liked player can generate a few more dollars and help those looking for treatments or cures FIND one...then the loss is easier to bear.
