My brother-in-law who is a doctor turned me on (can't finish the sentence here) to a great website: www.Ted.com.
SOOOOOO, worth it! I was a little, ok a lot, unmotivated to check it out, but it is very cool. The first one you should watch is "A Stroke of Insight." It is about a neuroscientist's experience of having a stroke. Once she realizes she's having a stroke, she realizes how incredibly cool it is that she is experiencing what she researches. Trust me. It is 20 min well-spent. And there are so many more to watch, and not enough time!
