News flash: Bill O'Reilly is not very bright.
Last night on the O'Reilly Factor, Bill turned to the audience letters. From Peter in Canada: "Has anyone noted that life expectancy in Canada under our health system is higher than the USA?" Bill wasn't phased, but he did use some creative math to answer. "Well Peter, that's to be expected," he said, "we have ten times as many people as you do!"
There is actually an interesting point here: up to a certain point, population density decreases your life expectancy quite dramatically. But I'm pretty sure that Bill O'Reilly was not making that interesting point. I'm pretty sure he was saying something incredibly innumerate.
