Around 80,000 of us are sent to the hospital each year by what many see as man's second best friend—the lawnmower. This usually happens after a stick or a rock ricochets off the blade of our dear old John Deere, flies through the air, then shoots us right in the eye. But other injuries are even more gruesome, including the occasional fractured (or missing) foot. Keep in mind that, according to a study conducted by the Johns Hopkins Bloomberg School of Public Health, the majority of lawnmower injuries happen to children younger than 15 and adults over 60. So think twice next time Junior or Great Grandpa asks if they can help out by mowing the lawn. And take care of your own face by wearing safety goggles.
