This is the best video I've seen on line in awhile. Two days ago at a lecture I went to for Nike they showed us a similar version that they had cut down, but this is what it was based off of. Both of them had similar information, but not as much as this video. I really like it. Its has some interesting facts. Some of you might have seen it already, but its still cool.
