Boston Tragedy

Shocked and saddened by the explosions in Boston today.

Not much I can do from here but this: I am going this weekend to donate blood. If you can donate blood, please do. US blood supplies are pretty much always low; probably other countries' supplies too.

PS. No jokes about this event, please. I don't expect anyone on my friends' list to do so, but if you were thinking about it, please don't.
