I guess I'm going to be giving you another video or two tonight, because I have to go chase down the lung I just coughed up. Come back, lung!
I'm picking from the HowStuffWorks suite of shows, specifically Stuff Mom Never Told You (hosted by Cristen Conger), and supplying you with two videos. The two get into the topic of hair length: namely, why it is, culturally in the West, supposed to be short hair for men and long hair for women. Something you've probably wondered about yet never cared enough to go look it up. Well, there you go. Have at it.
