“…from the age of thirty or forty on, after we’ve spawned, we’re living on time that evolution regards as pointless. … ‘if you just kept aging at the rate you age between twenty and thirty, you’d live to be a thousand. At thirty, everything starts to change.’ From that point, our risk of mortality doubles every seven years.”
