11. Wearing shorts during a flight
Sometimes people decide to wear shorts during a flight either because of the hot weather or their destination, but there are several issues with this. To start off, airplanes are not cleaned between flights and since most germs, mites, and bacteria reside in the chairs, you are exposing your skin and possibly areas of your body to several dangers.
Secondly, when people are crammed into a small space, it can create discomfort because of bad body odor. Even when you shower before a flight, sitting in a chair for long hours can inevitably lead you to sweat which can result in an unpleasant odor coming from your skin.
