Right now, at this very moment, all across the plan­et, there are 7.6 bil­lion human beings eat­ing, breath­ing, sleep­ing, brush­ing their teeth, walk­ing their dogs, drink­ing cof­fee, walk­ing down the street or run­ning onto the sub­way or hop­ping in their car, maybe read­ing a sum­ma­ry of a pod­cast they’re about to hit play on … and the num­ber is only going up. Every­day 386,000 babies are born (16,000 an hour). We’re adding a bil­lion new peo­ple every 12 years.

So here’s a ques­tion you’ve prob­a­bly nev­er thought about: Are there more peo­ple alive right now than have ever lived on the plan­et in his­to­ry? Do the liv­ing out­num­ber the dead? Robert got obsessed with this odd ques­tion, and in this episode we bring you the answer. Or, well, answers.
