Brain-eating amoebas are back! And right on time! Every year since 1960, the Centers for Disease Control and Prevention logs between four and five fatalities, usually during the summer when people routinely dunk their heads into warm, untreated freshwater. Brain-eating amoebas then slither up their noses and chow down on their brains—rarely leaving behind any survivors.

Brain-eating amoebas are unpleasant.

As a matter of fact, contracting a brain-eating amoeba is so rare that shark attacks, lightning strikes and even coconuts kill more people every year than the dreaded brain-eating amoeba. That doesn’t make them any less terrifying because they still eat your brain, but it should answer the totally unnecessary question of whether Slip-n-Slide is too dangerous for kids.

At least 25 people every year end life to the sound of popping champagne—which must really put a damper on the festivities. For your vacation viewing pleasure, here’s a kill count (based on deaths per year) for the summer activities least likely to end your life:
