20.04-An incredible system! The human body-2016-06-16

The objective of this website, on Today’s Personal Computing, is to help you better understand, select, use and take full advantage of the recent Information Processing Technologies. It often shows sophisticated functionalities available on these technologies which sometimes may appear to be almost superhuman. People are impressed by the sophistication and possibilities offered by these technologies.

Many are wondering if these technologies will not one day replace humans. Having spent nearly 50 years observing the evolution and working with these technologies, I can assure you that we are very far from reaching that stage. Nothing that these technologies do has not been preprogrammed by humans. To convince yourself and provide a perspective on the incomparable sophistication of the human body, let me introduce you to a brief overview of what happens in a single day within our human body. 


As time goes by, we sometime feel like our body is beginning to creak and fail us on the outside, but do we ever stop to consider the incredible work that is taking place inside of it every day? There is so much going on and everything fits together so well, that it’s almost impossible to comprehend. The following will remind you that there are miracles going on inside our body every single day. Here is what goes on:

  • Your heart pumps approximately 2,000 gallons US (7,571 liters) of blood through its chambers every, single day. It beats more than 100,000 times a day to achieve this incredible feat.
  • Every day your body, ensures you don’t contract cancer thousands of times over. Cancer is formed when cells are altered in a way which re-programs their DNA and it’s estimated that tens of thousands of cells suffer cancer-causing lesions every day. But the body sends special enzymes scuttling around to inspect DNA strands for faults and fix them before they turn into tumors.
  • Your brain doesn’t stop working. It’s estimated that about 50,000 thoughts bass through it each day on average, although some scientists put the figure closer to 60,000. That is a whopping 35-48 thoughts every minute.
  • The cells in your stomach lining produce an alkaline substance every few milliseconds to neutralize stomach acid. If they didn’t do this, your stomach would digest itself because some of the acids are strong enough to dissolve metals.
  • You blink about 28,800 times every day, with each one lasting just a tenth of a second. This is a voluntary reflex the body uses to keep the eyes clean and moist, which is pretty crucial given that 90% of the information you process is visual, and you can weigh up any visual scene in just 0.01 seconds. Consider how many people and objects you look at every day – It’s remarkable!
  • Most of the body’s energy is expelled via heat. Your body produces the same heat as 25 light bulbs over the course of a single day. La majeure partie de l’énergie du corps est expulsé par la chaleur. Votre corps produit la même chaleur que 25 ampoules au cours d’une seule journée.
  • Red blood cells literally shoot around the body, taking less than 60 seconds to complete a full circuit. This means that each of yours makes 1,440 trips around your body every day, delivering oxygen and keeping your body energized. Each cell lives for about 40 days, before being replaced by a younger model. It’s no surprise their life span is short, having made 60,000 trips around the body, they must be exhausted!
  • You shed more than 1 million skin cells every single day but they are constantly replenished automatically, to save you from turning transparent and becoming rather exposed! Your skin is actually an organ; in fact, it’s the largest organ you have, with a surface area of 18 square feet (1.67 square meters).
  • Your hair (if you still have any) grows about half a millimeter per day. The average adult, with a full scalp, has around 100,000 hairs on their head. That’s a combined 164 feet (50 meters) of hair growth every, single day.
  • The brain and mouth work together to allow us to speak an average of around 5,000 words a day. Well that’s if you’re a woman, because studies suggest that men only speak 2,000 words a day, yet both sexes utter 500-700 of real value (i.e. that get a job done, or provide useful information).
  • Your liver is so busy over the course of a day; it is almost impossible to summarize its activities. It manufactures cholesterol, vitamin D & blood plasma; it identifies the nutrients your body needs, and stores some away for future use; it filters 3.06 US pints (1.45 liters) of blood every minute and produces 2 US pints (0.95 liters) of bile every day to help you break down your food. Basically, you have a factory plant running inside of you every day, which is pretty amazing!
  • The glands in your mouth produce an incredible 3.17 US pints (1.5 liter) of saliva every day. That’s a lot of dribble! If this didn’t happen, your mouth would dry up and become overrun with bacteria, and you wouldn’t be able to digest your food.
  • The average male’s testicles manufacture 10 million new sperm cells every day. Those that aren’t used age and are eventually broken down inside the body, with any useful nutrients being absorbed and put to use.
  • Each of your kidneys contains 1 million tiny filters that work together to filter an average of 2.2 US pints (1.04 liter) of blood every minute — that’s 3.17 US pints (1.5 liters) every single day, despite each kidney only being the size of a fist. If that wasn’t enough, they also expel an average of 2.5 US pints (1.18 liters) of urine from your body every day also.
  • You grow 0.315 inch (8 mm) every night while sleeping, before shrinking back down again the next day. This saves you from some pretty hefty clothing bills and ensures you don’t have to raise the door frames every year or two.
  • Your body works over time to digest your food and the process starts before it even hits the mouth. When you smell food, your mouth automatically produces more saliva to prepare the digestive system for work. It takes about 6-8 hours for food to pass through the stomach and two days to complete the digestion process. The average person will eat over 50 tons of food in his or her lifetime, which seems ridiculous!
  • And most amazing of all, your body cells are regenerating themselves every single day without any prompting. This means you have an entirely new set of taste buds every ten days, new nails every 6-10 months, new bones every ten years and even a new heart every 20 years.

So next time you think that your body is starting to creak, just think about all the incredible things that are happening inside it every day, because our living reality is close to a miracle!

You will agree with me that before computers reach a comparable level of sophistication to the human body, which I believe will never be reached, a lot of water will flow through the St. Lawrence River and the Mississippi! Beware of humans! Don’t be afraid of taking full advantage of today’s technologies!
