(Newser) – Planet Earth is going to get its 7 billionth person in coming days, and the BBC marks the occasion with a calculator that estimates what your number is in that mass of humanity. You plug in your birth date, and it computes the figure, along with how many people came before you since the dawn of history. The calculator is here.
