A new drug reduces the risk of heart attacks by 40%. Shark attacks are up by a factor of two. Drinking a liter of soda per day doubles your chance of developing cancer.

Gerd Gigerenzer explores the difference between relative and absolute risk. [Directed by Visorama, narrated by Addison Anderson].
