Do you know where you fit in chronologically with the seven billion or so human folk running around sweet Terra? BBC has a really cool tool that lets you plug in your birthday to get an approximation of which number human you were to sprout up on the planet.

The calculations are all based on estimates from the UN Population Division, and the tool itself is prompted by our estimated worldwide population hitting that seven billion mark some time over the next few weeks. Even crazier though is that the UN's figures have us thisclose to ten billion Earthfolk by 2050, which world be sorta terrifying if we weren't going to meet our fiery apocalyptic end next year.
