Modern lifestyles are actually a fairly unnatural way for a human to live. Living in such an unnatural way does create problems with functioning because, in many ways, societal and cultural norms and behaviours go against our own genetic and biological wiring.
Diet is one example. The foods that we eat now are vastly different from those we evolved to eat. Grains were not a major part of our ancestors diet and neither was tooth decay (apparently)...that's a modern problem brought about by a high carbohydrate diet which we have only been consuming for the last 10 thousand years or so. For hundreds of thousands of years before that our diet was very different. According to isotope studies done on bones from palaeolithic fossilised remains our ancestors also consumed larger amounts of many micro-nutrients than we do and, in some ways, they were stronger, faster and healthier than we are. They also had much better teeth..they were worn down from eating abrasive foods, but they were not rotten even though they had no dentists or toothpaste!
Another is the way we are all crammed up into cities, exposed to modern day forms of stress that just did not exist when our species was evolving. The fight or flight system we genetically inherited was not designed for the lifestyles we lead and basically cannot cope as it has not yet adapted. So mental health problems are on the rise as a result.
Human cities have been likened to Human zoos. In a regular zoo, animals in captivity will start to suffer from something called stereotypy, where they adopt repetitive pointless behaviours in order to cope with the stress of captivity. Humans can do the same, only in our culture they are branded as mental illnesses and medicated.
How many disorders really are disorders given that our lifestyles have become so unnatural and would they still be disorders if we still lived the primitive lifestyles we are genetically adapted to life?
I was just reading something about what you just said before I came back to my topic. XD
