8 VERY COOL FACTS ABOUT THE HUMAN BODY
The human body is an incredibly complex and intricate system, one that still baffles doctors and researchers on a regular basis despite thousands of years of medical knowledge.
As a result, it shouldn’t be any surprise that even body parts and functions we deal with every day have bizarre or unexpected facts and explanations behind them. From sneezes to fingernail growth, here are 100 weird, wacky, and interesting facts about the human body.
1. The Brain
The human brain is the most complex and least understood part of the human anatomy. There may be a lot we don’t know, but here are a few interesting facts that we’ve got covered.
Nerve impulses to and from the brain travel as fast as 170 miles per hour. Ever wonder how you can react so fast to things around you or why that stubbed toe hurts right away? It’s due to the super-speedy movement of nerve impulses from your brain to the rest of your body and vice versa, bringing reactions at the speed of a high powered luxury sports car.
2. Hair and Nails
While they’re not a living part of your body, most people spend a good amount of time caring for their hair and nails. The next time you’re heading in for a haircut or manicure, think of these facts.
Facial hair grows faster than any other hair on the body. If you’ve ever had a covering of stubble on your face as you’re clocking out at 5 o’clock you’re probably pretty familiar with this. In fact, if the average man never shaved his beard it would grow to over 30 feet during his lifetime, longer than a killer whale.
3. Internal Organs
3. Internal OrgansThough we may not give them much thought unless they’re bothering us, our internal organs are what allow us to go on eating, breathing and walking around. Here are some things to consider the next time you hear your stomach growl.
The largest internal organ is the small intestine. Despite being called the smaller of the two intestines, your small intestine is actually four times as long as the average adult is tall. If it weren’t looped back and forth upon itself it wouldn’t fit inside the abdominal cavity.
4. Bodily Functions
We may not always like to talk about them, but everyone has to deal with bodily functions on a daily basis. These are a few facts about the involuntary and sometimes unpleasant actions of our bodies.
Sneezes regularly exceed 100 mph. There’s a good reason why you can’t keep your eyes open when you sneeze–that sneeze is rocketing out of your body at close to 100 mph. This is, of course, a good reason to cover your mouth when you sneeze.
5. Sex and Reproduction
As taboo as it may be in some places, sex is an important part of human life as a facet of relationships and the means to reproduce. Here are a few things you might not have known.
On any given day, sexual intercourse takes place 120 million times on earth. Humans are a quickly proliferating species, and with about 4% of the world’s population having sex on any given day, it’s no wonder that birth rates continue to increase in many places all over the world.
6. Senses
The primary means by which we interact with the world around us is through our senses. Here are some interesting facts about these five sensory abilities.
After eating too much, your hearing is less sharp. If you’re heading to a concert or a musical after a big meal you may be doing yourself a disservice. Try eating a smaller meal if you need to keep your hearing pitch perfect.
7. Aging and Death
From the very young to the very old, aging is a necessary and unavoidable part of life. Learn about the process with these interesting, if somewhat strange facts.
The ashes of a cremated person average about 9 pounds. A big part of what gives the human body weight is the water trapped in our cells. Once cremated, that water and a majority of our tissues are destroyed, leaving little behind.
8. Human Body Disease and Injury
Most of us will get injured or sick at some point in our lives. Here are some facts on how the human body reacts to the stresses and dangers from the outside world.
Monday is the day of the week when the risk of heart attack is greatest. Yet another reason to loathe Mondays! A ten year study in Scotland found that 20% more people die of heart attacks on Mondays than any other day of the week. Researchers theorize that it’s a combination of too much fun over the weekend with the stress of going back to work that causes the increase.
