Under Pressure

Happy Thanksgiving. Anyways, the only thing I do on Thanksgiving is play video games, eat, and watch some football. The last of the three NFL games on Thanksgiving was the Broncos vs the Giatns in Denver, the mile high city. Being in that altitude makes some players have those oxygen masks since the air is so thin since their altitude is higher. That also has some stuff to do with atmospheric pressure. Everything in the Earth's atmosphere is under atmospheric pressure, but depending upon where a person is located, the pressure varies. Even though most people think air is nothing, air has mass, which is why atmospheric pressure occurs since all the air is pushing down on you. So most people can't even notice it, but when they change altitude, sometimes their ears pop, which is because of the varying pressure outside and inside their body. That can be why ears pop, headaches occur, sinus pressure happens, and most of all atmospheric pressure, all because of air.
