We have a lot to learn about the human body

Athens — The human body is a complex system. The body still baffles doctors and researchers, despite all their medical knowledge.

Here is something to think about. It is hard to grasp just how small the atoms that make up your body are until you take a look at the sheer number of them.

An adult is made up of around 7,000,000,000,000,000,000,000,000,000 (7 octillion) atoms. Who do you think counted those atoms?

There are more interesting facts about the human body you may  or may not know.  I obviously did not know, or I would not have done so much research.

Let's start with the brain.  Did you know the brain operates on the same amount of power as a 10-watt light bulb?

This is true, your brain generates as much energy as a small light bulb, even when you're sleeping. This could be the reason when you get something they say “The light bulb just went off.”

This must not be true for everyone. The human brain cell can hold five times as much information as the Encyclopedia Britannica. I have met people, that may make a good argument for this information being false.

Your brain uses 20-percent of the oxygen that enters your bloodstream. This is what is interesting – the brain only makes up about 2-percent of our body mass, yet consumes more oxygen than any other organ in the body. Everyone take a deep breath to keep you brain healthy.

The brain is much more active at night than during the day. Not my brain. The scientists that know say when you turn off, your brain turns on.

All your high IQ people dream more than those of us with a normal IQ. The reason you don't remember most of your dreams is because they only last two to three seconds.  That’s not enough time to register. You just think they last all night.

While it may seem the brain is the nerve center, it cannot feel pain. The brain is surrounded by loads of tissues, nerves and blood vessels that are plenty receptive to pain.

Your brain is 80-percent water. The brain is squishy, pink and jelly-like. Drink plenty of water to keep that brain of yours hydrated.

Other interesting facts about the human body that I found interesting:

•  The fastest growing nail is on the middle finger;

• Blondes have more hair;

• Fingernails grow nearly four times faster than toe nails;

•  Lifespan of a human hair is three-to-seven years;

• The human heart creates enough pressure to squirt blood 30 feet;

• The acid in your stomach is strong enough to dissolve razor blades;

•  The human body is estimated to have 60,000 miles of blood vessels;

• You can get a new stomach lining every three to four days;

• The surface area of a human lung is equal to a tennis court;

• Women's hearts beat faster than men;

• According to some scientists, your liver has over 500 functions;

•  The aorta is nearly the diameter of a garden hose;

•  Sneezes exceed over 100 mph;

• A cough can travel 60 mph;

• Feet have 500,000 sweat glands, and can produce more than a pint of sweat a day;

•  During your lifetime, you will produce enough saliva to fill two swimming pools.

Did you know the three things pregnant women dream most of during their first trimester are frogs, worms and potted plants? I don't get the potted plant dream.

Your pets are not the only ones shedding. Humans shed about 600,000 particles of skin every hour.  That works out to about 1.5 pounds each year. So the average person will lose around 105 pounds of skin by age 70.

This is something people don't like to talk about. Did you know that most people have eyelash mites? These mites live heads-in in your eyelash follicle (the pores where hair grows), feeding on sebaceous excretion and dead skin cells.

They come out to the skin surface at night to mate and return to the follicle to lay their eggs! The eggs hatch and what do you get? – baby mites!

Our scientific understanding of the human body is certainly much better than it used to be, and people are living longer than ever.

We still don’t know everything about our bodies yet, despite the fact that we live in them every day. There are still mysteries to solve and new things to discover.

  • Wilson mug.JPG Rolling into something new

    She did it.
    My baby girl rolled over for the first time this past week while daddy and mommy were watching closely.
    As other major news broke across the county, watching my baby roll over for the first time was by far the biggest news of the week for me. Odd.

  • Joe new mug.jpg Fanfare is a time to prepare for another season

    I love to see the talent our student athletes have across Henderson County. To know that each player puts in the blood, sweat and tears to play for a district championship and hopefully a state title is something special to see.
    Another great in the world of sports is a player who is retiring this season in New York Yankees shortstop Derek Jeter.
    Jeter once said, “There may be people who have more talent than you, but there's no excuse for anyone to work harder than you do — and I believe that.”

  • kathi New  copy.jpeg The greatest country in the world has hungry children

    No child should go hungry. We are the greatest country in the world, yet we have hungry children.
    An article I recently read said that if a child in school can't afford lunch, they will be given a sandwich and water. I was told the sandwich is cheese between two pieces of bread.
    I hope everyone realizes that is what they serve in the county jail. Not that I know this from personal experience. I was told from someone who did know from experience.

  • Wilson mug.JPG Hakuna Matata, what a wonderful phrase

    Hakuna Matata! What a wonderful phrase.
    Hakuna Matata! Ain't no passing craze.
    It means no worries for the rest of your days.
    It's our problem-free philosophy.
    Hakuna Matata!
    Congratulations, if you have watched the Lion King a couple of times you now have this song stuck in your head for the rest of the day.

  • Jeff's mug.jpg It was a week in the depth of heat, then cooler

    Sunday and Monday of this week have been very uncomfortable.  The air conditioner at our house has been down, and the temperature outside and in the house have been way up.
    Thank God for the blessing of the cool temperatures and the rain that fell on Tuesday, then on Wednesday.  It changed things just a little bit.

  • Time away is necessary for everyone

    I can remember as a kid writing essays on “How I Spent My Summer Vacation.” As the years pass, and we are more in-tune with the workplace, those vacations get shorter and shorter.
    Do you ever have those days  when you just need a vacation? Sometimes you just need to get away.
    Taking time off work should be fun and rejuvenating. We all need a recharge every now and then. But vacations aren't what they use to be. We rarely disconnect ourselves from our jobs.

  • Joe new mug.jpg Student athletes: Time to wake up and get to work

    Hey student athletes, it is about time for you to wake up and get to work.
    Your summer is coming to an end, and the early morning wake up calls for practices are right around the corner.
    I am talking to the football players, volleyball players, cross country kids, band members, drill team members and cheerleaders.

  • Wilson mug.JPG Remember who you are

    Are you running so fast that you have forgotten why you started the race in the first place?
    Life moving at a blistering pace that it is tough to keep up?
    Maybe it is time to stop, take a deep look into the pool of water and remember. Remember who you are.
    On numerous occasions, I have had to do just that. Ironically, various movies have caused me to look inside.

  • Jeff's mug.jpg CSUMC provided a memorable experience

    My wife Jean and I went to a very interesting, and what I consider a very unique event last Saturday night.
    I had heard that the church where we are members, Carroll Springs United Methodist Church, was having an event in which people sitting in the audience would sing their favorite hymns into a microphone.

  • Rich mug.jpg Independence ultimately won on battlefield

    I always enjoy celebrating Independence Day, and hearing some of the stirring words written in the Declaration of Independence.
    Thomas Jefferson wrote that our Creator has given us certain rights, life, liberty and the pursuit of happiness. The way I see it, if I have life and liberty, that gives me a pretty good start on the third one.
    But as eloquent as our founding fathers were, and how moving the texts they left behind, one fact can’t be overlooked. Our independence was ultimately won and secured on the battlefield.
