That's a Stuff You Should Know podcast, and I feel that half of you are thinking: I don't have time to listen to a podcast, and if I did, I wouldn't listen to something science-related from people who use "less" where it's supposed to be "fewer."
But: I love the Stuff You Should Know podcast guys. They're very pleasant and relaxing to listen to. So the podcast method of acquiring information is exactly what's best under certain circumstances. (I listen to audiobooks when I'm walking and can give my full attention but I like podcasts when I'm getting dressed in the morning and making my toast and coffee.)
