BBC Dimensions’ site called How Many Really? is incredibly eye-opening and fascinating. Basically, by allowing the site to connect to your Facebook or Twitter account, the BBC breaks down historical events — wars, disasters, civilizations, diseases, modern society, etc. — in an easy-to-swallow number that’s more directly related to the number of friends you have.
