Risk is a very much misunderstood concept, and it's important to remember that it's not just a measure of how serious a problem could be, but how likely it is to happen, too. This video attempts to hammer that home, though the universal medium that is... song.

It's not dissimilar to the Periodic Table Song, but instead it lists a glorious 108 different things that could kill you. But don't worry: some are incredibly threatening but unlikely to affect you, while other are very common but ultimately shouldn't cause you too much trouble. As the song says: you'll need a dose of exposure before you have anything to worry about. [Risk Bites]
