くしゃみのスピードは時速160km！？
When we sneeze, the air that comes out of our nose and mouth can reach speeds of up to 160 kilometers per hour! That’s as fast as a bullet train in Japan. A sneeze is very short?it lasts less than a second?but it is very powerful. Because sneezes can spread germs quickly, it’s important to cover your mouth with your hand or elbow when you sneeze. This simple habit can help protect the people around you!
