Strokes In The Media

You know, strokes are getting really popular in the media.  Last week, Grey's Anatomy featured a character (who couldn't have been more than 35) who was having a stroke.  The guy walked in with a migraine and was discharged and then caught right before he got into his car by Meredith to come back in because Lexie didn't diagnose him properly.

Why do strokes keep popping up in shows and news featuring just new people?  I'm beginning to think that something is in the water or in our food that is causing this.  Seriously...can you remember strokes being in the news so much?
