 Welcome to Risk Bites. If you've ever wondered about the science behind risk and safety, this is the place for you. Here we will be posting bite-sized videos of really cool stuff on everything from making sense of the latest risk scares to understanding why smart people do stupid things. We'll mainly talk about risks that affect your health, but we may slip in some other cool stuff as well. We'll also be talking about benefits as well as risks because, quite frankly, you can't have the one without the other. Risk Bites videos are going to be short. We have, I'm sorry to say, the attention span of a flea, so don't expect anything longer than 60 seconds. Many of the videos will be crude doodle vids like this. The script says that this technique used by YouTube greats like Viheart and Henry Reich is fantastically effective. Personally, I think it's just because we're lousy artists. Occasionally, though, we'll mix it up by talking with incredibly interesting people about their incredibly interesting research. At least it will be when we've finished with it. So if you have a burning need to know how dangerous eating a banana is compared to living next to a nuclear power plant, or whether drinking water out of that plastic bottle is a really bad idea, please subscribe. We'll be posting a new Risk Bites every week, starting November 2012. See you there.
