What's in a year?

Some anniversary posts are less than intriguing, but I really like this celebratory video from Joe Hanson and the folks at It's Okay To Be Smart. In commemoration of the series' first year on YouTube, they've put together a nifty summary of the biological changes that happen to a human body over the course of a year and the different ways of building calendars based on astronomical phenomena. If you've ever wanted to find out how much the average person poops in a year AND learn how long it takes a constellation to travel across the sky and back in the same video ... here you go. Bonus, I really think Analemma has potential as a hot, new baby name.
