Like I said, a quick Google will show up a couple of quite reputable studies that question the claim that there's a causal relationship. It's not as cut and dried as the interviewer makes out. Which is fair enough - he's a comedian, not a journalist, and there's no reason to let facts get in the way of a good joke.
We can have an in-depth discussion about it if you like, but I'd rather not do it via Tapatalk. Also this is probably neither the thread nor the forum for it.
