Â­In this article, we will take a very close look at networking, and in particular the Ethernet networÂ­king standard, so you can understand the actual mechanics of how all of these computers connect to one another. 1. 2.
Sneezes protect your body by clearing the nose of bacteria and viruses, Kao explains. When something enters your nose or you encounter a trigger that sets off your sneeze center in your brain, located in the lower brain stem, signals are rapidly sent to tightly close your throat, eyes, and mouth. Next, your chest muscles vigorously contract, and then your throat muscles quickly relax.
Some people believed that a sneeze causes the soul to escape the body through the nose. Saying bless you would stop the devil from claiming the person's freed soul. Others believed the opposite: that evil spirits use the sneeze as an opportunity to enter a person's body. There was also the misconception that the heart momentarily stops during a sneeze (it doesn't), and that saying bless you was a way of welcoming the person back to life. We now know that sneezing is a reflex action and is most often the sign of something relatively benign, such as a cold or allergy.
