The redneck strike again.

[Confused Ape]

The nervous system in the humans change all the time according to
place and time in which we live.
You take a kid of today used to deal with computers and other technological things and you put him back in time 3-4 hundred years
were they use to do manual jobs that require little intellect.
He would go mad.

Also a kid from that age that would come in this age and deal with today technology would go mad as his nervous system could not deal with today way of life.

It would be very difficult for anyone to adjust if they suddenly found themselves transported to a different point in time.

There are still manual jobs today which require little intellect. There were jobs in the past which required skill and intellect. I found an interesting article on the School of Mathematics and Statistics University of St Andrews, Scotland.

Mathematics and Architecture

Nobody is entirely sure how much maths went into constructing the pyramids but maths was definitely required later on. So was engineering. They didn't have computers to help them either.

History of Computing - Abacus

With the complex adding systems that we have today, it can be hard to grasp that peoples were using small stones or other objects as numerical devices from time immemorial. The word calculate itself comes from the Latin calculus, which means small stone. These methods of calculations introduced some elementary kind of abstraction, but people gradually realized that this method did not go far enough to satisfy their increasing needs. To count up to 1000, for example, they would have had to gather a thousand pebbles, which was enormous work.

That is why, once the principle of the numerical base had been grasped, the usual pebbles were replaced with stones of various sizes to which different orders of units were assigned. For example, if a decimal system was used, the number 1 could be represented by a small stone, 10 by a larger one, 100 by a still larger one, and so on. It was a matter of time someone to think of to arrange some pebbles over a big flat base stone, wire or something else.

It is unknown when exactly were developed first devices to facilitate calculation, such as the counting board, or abacus. The counting board was invented when someone grasped the idea of placing pebbles or other objects in columns marked on a flat surface, and assigning an order of units to the objects in each column. Later, loose objects in columns were replaced with beads that could slide along parallel rods.

My father was born in 1899 and he died in 1989 - he lived to see the lunar landings and the very first home computers without going mad. I was born in 1949. If I was transported back to the 1950's I'd go mad without my computer even though I was a child in that decade and remember it well. Yes, my nervous system has changed because it does as one grows older but that has nothing to do with how my environment continually changed throughout my lifetime.

I've done a lot of googling to find out if people had different nervous systems in the past. All I could find was - A istory Of The Nervous System. This is just a history of how people came to understand the nervous system.

In the fourth century B. C., the Greek philosopher Aristotle believed firmly that the nerves were controlled by and originated in the heart because it was, in his interpretation, the first organ of the body and the seat of all motion and sensation. Not surprisingly, he was misled by his confusion between ligaments and nerves in drawing this conclusion. Six centuries later, the Roman physician Galen contradicted him, disparaging those "who know nothing of what is to be seen in dissection." Instead he concluded that the brain was the most important organ of the body, with the nerves emanating from it:

Aritstotle was wrong. The humans nervous system didn't alter after Aristotle's time period.

As the nervous system change also the system to deal with diseases change so what was good in the past is no longer good these days.

There is evidence that the immune system and nervous system are linked but I've come across nothing to say that anything's changed over the past few thousand years.

The Immune System and the Nervous System

Evidence is mounting that the immune system and the nervous system are linked in several ways. One well-known connection involves the adrenal glands. In response to stress messages from the brain, the adrenal glands release hormones into the blood. In addition to helping a person respond to emergencies by mobilizing the body’s energy reserves, these “stress hormones” can stifle the protective effects of antibodies and lymphocytes.

Another link between the immune system and the nervous system is that the hormones and other chemicals that convey messages among nerve cells also “speak” to cells of the immune system. Indeed, some immune cells are able to manufacture typical nerve cell products, and some lymphokines can transmit information to the nervous system. Moreover, the brain may send messages directly down nerve cells to the immune system. Networks of nerve fibers have been found connecting to the lymphoid organs.

When it comes to disease, however, populations can develop an immunity to some diseases which are still deadly to human societies which have never been exposed to them.

Uncontacted Tribes - The Threats

Introduced diseases are the biggest killer of isolated tribal people, who have not developed immunity to viruses such as influenza, measles and chicken pox that most other societies have been in contact with for hundreds of years.

One of the Murunahua survivors, Jorge, who lost an eye during first contact, told a Survival researcher, ‘The disease came when the loggers made contact with us, although we didn’t know what a cold was then. The disease killed us. Half of us died. My aunt died, my nephew died. Half of my people died.’

I can't find any studies showing that isolated tribal people have different nervous systems, though.

As for what was good in the past, umpteen millions of people died from bubonic plague. These days the chances of survival are a lot greater due to antibiotics, especially if the patient is treated within 24 hours.

If we go back 2-3 thousand years when the acupuncture was invented then the difference is even more dramatic.

It is? How do you know that acupuncture was more effective 2-3 thousand years ago? Can you provide a link to a reputable medical source explaining it?
