The CDC has released a new Fact Sheet on Concussions. I've been seeing a lot of info about concussions in the news lately, and I think that's a good thing.
When I went to their website to have a look at it, I found not only that fact sheet, but a source of one of my most favorite things: Free Information. The National Center for Injury Prevention offers a LOT of free materials, just for the asking.
How did I not know about this before?
They even offer electronic copies of things that are out of print.
There's a limit of 18 publications per order, but as far as I can see nothing to keep you from coming back until you've ordered everything you're interested in.
