You can't sneeze with your eyes open...and other trivia of the human body

Some people sneeze with their eyes open and some don’t, so really the title of this post is false--but it has been widely believed. According to studies, we have no control over whether or not we close our eyes when we sneeze, though. It’s a reflex, just as sneezing is--and, no, your eyeballs won’t pop out if you don’t close your lids.

Check out these other interesting facts about the human body:

• Coughs release a burst of air moving at speeds of up to 60 mph, while a sneeze can exceed the speed of 100 mph.
  
• The average human scalp has approximately 100,000 hairs and loses an average of 40 to 100 strands per day. Also, blondes have more hair than people do with dark hair.
  
• Babies are born with 300 bones, but adults have only 206 in our bodies. The reason? Some bones fuse together as a baby grows.
  
• Every person has a unique tongue print.
  
• Most people lose half of their taste buds by the time they’re 60 years old.
  
• Lack of sleep will kill a person faster than starvation. You can live a few weeks without food, but only about 10 days without sleep.
  
• It takes 43 muscles to frown and only 17 muscles to smile.
  
• Laughing lowers stress hormone levels. Laughing also strengthens our immune system. Children typically laugh an average of 300 times a day while adults only laugh between 15 and 100 times per day.
  
• Historically, it was believed that men spoke only 7,000 words per day, and women spoke nearly 20,000. Not so, according to researchers who say that both men and women typically speak about 16,000 words per day.
  
• If a person goes blind in one eye, they lose about one-fifth of their vision, but all of their depth perception.
