Okay, so this video has been posted probably on thousands of blogs already, but you know what, I don't care. Hans Rosling gives an amazing talk on poverty and life around the world, and he uses his interactive exploratory tool, Trendalyzer (acquired by Google), to show the different levels of health, education, and money around the world. Trendalzyer: useful, yes, but not the main point of the talk. Watch Rosling's talk all the way through. You won't be disappointed.
