Facts

It’s the end of January, the everlasting month which has got to have at least 54 weeks, or so it seems. You’ve been hard at work meeting the goals you set for yourself for the new year, and you may be pretty grouchy by this time.

So, take a breather and enjoy a few light-hearted minutes of interesting health-related trivia.

Did you know…

  • Your eyes blink around 20 times a minute. That’s more than 10 million times a year.
  • Your ears never stop growing!
  • Earwax is actually a type of sweat.
  • The tongue is covered in about 8,000 taste-buds, each containing up to 100 cells helping you taste your food.
  • In the U.S., two out of three people do not have perfect vision (20/20).
  • More germs are transferred by shaking hands than by kissing. Our hands come into contact with millions of germs and bacteria each day.
  • Lack of sleep can kill someone sooner than starvation. Chronic sleep deprivation is linked to a higher risk for cardiovascular disease, insulin resistance, obesity, and a host of other life-threatening conditions.
  • Ten percent of your body mass is made up of your blood. The average adult human blood supply clocks in at around eight to 10 pints or roughly five liters. As such, your body has enough iron to make a three-inch-long nail.
  • A quarter of human bones are found in the feet. One-fourth of all of the bones in your body are in your feet—which are made up of 26 bones and 33 joints each—for a grand total of 52 bones in each foot.
  • Humans are the only animals who cry when emotional. Other animals may shed tears, but they don’t do so out of sadness.
  • Most people produce enough saliva in their lifetimes to fill two swimming pools or about 500 bathtubs. Saliva protects our mouths from oral infections while also helping us begin digesting our food.
  • In most people, the left lung is 10% smaller than the right. This is because the heart takes up a significant amount of space on the left side.
  • Human noses can remember 50,000 different scents. Still, the human nose is not nearly as powerful as a dog’s, whose sense of smell is 1,000 to 10,000 times better than ours.
  • Our brains don’t feel pain. We have pain receptors and process pain signals in our brains, but the brain itself does not feel pain.
  • The tongue is the strongest muscle in the entire body. And like fingerprints, our tongues have a unique tongue print.
  • When we touch something, we send a message to our brain at 124 mph
  • The body has 2.5 million sweat pores. And those of us in South Mississippi have probably felt every one of them at one time or another.
  • If you walked for 12 hours a day, it would take the average person 690 days to walk around the world.
  • A sneeze generates a wind of 100 mi/hr, and a cough moves out at 60 mi/hr.
  • Our heart beats around 100,000 times every day or about 30 million times in a year.
  • Our blood is on a 60,000-mile journey per day.
  • Our eyes can distinguish up to 10 million color surfaces and take in more information than the largest telescope known to man.
  • The fastest growing nail is on the middle finger.
  • Our lungs inhale over two million liters of air every day, without even thinking. Their surface area is large enough to cover one side of a tennis court.
  • It is not possible to tickle yourself. When you try you are aware of the exact time and manner in which the tickling will occur, unlike when someone else tickles you.
  • When you blush, the inside of your stomach does too.
  • Enamel, found on our teeth, is the hardest substance in the human body.
  • The extra skin on your elbow, known at the weenus, is basically nature’s Silly Putty because there are fewer sensory neurons located there. That means you can keep kneading it all day long, and as hard as you want.
  • Your height differs depending on the time of day. You’re taller in the morning than you are in the evening because the cartilage between your bones compresses throughout the day.
  • Your fingernails grow three times faster than your toenails. Fingernails grow about three times faster because your hands have more blood pumping through them due to closer proximity to the heart, which facilitates growth.
  • The only part of the body that has no blood supply is the cornea of the eye. It receives oxygen directly from the air.
  • A newborn child can breathe and swallow at the same time for up to seven months
  • 50,000 cells in your body died and were replaced by new ones while you were reading this sentence.
  • By the end of a person’s life, they can recall, on average, around 150 trillion pieces of information.
  • Teeth are the only part of the human body which cannot heal themselves.
  • Only 7% of people are left-handed.
  • During their lifetime, a person will on average accidentally swallow eight small spiders.
  • Human beings are the only animals which can draw straight lines.
  • People with blue eyes are more sensitive to pain than others.
  • A person burns more calories when they are asleep than when they watch TV.
  • Children grow faster in the spring.
  • Our eyes remain the same size as they were at birth, but our nose and ears never stop growing.
  • Humans are the only animals with chins.

Keep plugging along at your goals. February is coming and with it brings a concerted effort to keep your heart healthy.
