Technology has made some aspects of life better. Some would say that one of these aspects is our health. I would disagree.
The Modern Diet
The modern diet consists of way too many calories usually in the form of carbohydrates and in particular refined sugars and starches which have a very high glycemic index. This is in ironic contrast with most of human history in which not getting enough calories was the problem. The modern diet also includes many unnatural chemicals which may or may not, depending on which studies you believe, have strange and undesirable side effects. Pioneer families like the Ingalls never had to understand, let alone pronounce, things like methylchloroisothiazolinone.
The dangerous effects of preservatives and other unnatural chemicals aside, even just the refined sugars and starches are enough to kill us. When you eat things like donuts or even the supposedly healthy cereals like Shredded Wheat you are sending way to much sugar into your blood stream. Sugar is necessary for your body to function, but too much sugar in you blood can destroy your blood vessels. The Insulin reaction, our bodies way of trying to save us from the dangerously high amounts of glucose in our veins, causes us to get fat by making the fat stay in our fat cells so the hungry cells can burn up the sugar first.
Today, mostly due to globalization, there is a greater number of fruits and vegetables available at your local supermarket. Unfortunately most of them are full of pesticides and contain far less nutrients than they used to decades ago. Similarly with vitamins and supplements, there is a greater variety and availability, but you wouldn't need most of them if you just had nutritious food at every meal.
Before the industrial revolution all work was done by either humans or animals. This naturally required large amounts or energy from food. For the average working stiff getting fat was not a concern. Today because of desk jobs and a generally more sedentary lifestyle most people are concerned about being overweight.
Sure we have gyms on every corner and even inexpensive exercise equipment at Walmart and if you live in a relatively safe neighborhood you can always take a walk, but most of us find it hard to make the time to get enough exercise to keep a healthy weight. If you are burning calories as you are making a living that time crunch goes away. So I would say technology doesn't make up for the much more accessible exercise as you work method of the past.
Stress has been a part of the human condition ever since our first
parents decided to leave the safety of their creators protective
headship. There has always been crime, poverty and war, but the level of
stress felt by most, whether living in a developed country or the third
world is much greater than it has ever been. Obviously things like
drought, famine and civil war are stressful. Africa and Asia have seen
more than their share of this. Like wise corruption and narco gangs are a
terrifying specter to live under, just ask anyone from Mexico or much
of Latin America. But its also no picnic living under the corporate
oppression and economic uncertainty in the U.S.
Technology has not helped in this regard. Modern life in the U.S. and other developed lands has generally been made more stressful by technology. In fact much of our stress comes directly from technology, such as the constant interruptions and demand for our attention that the proliferation of media and communications affords.
A more indirect effect of technology is the way it allows us to be independent and live almost anywhere. At first this sounds great, but then there is the natural consequence that most of us live amongst strangers. Our family members live far away and most of us don't know all if any of our neighbors. This also contributes to stress and for some depression and a sense of disconnectedness.
While its true that much technology has been devoted to safety, its also true that much of it wouldn't even be necessary if it wasn't for some other dangerous technology. A perfect example is seatbelts & airbags. Great ideas and I'm glad they were invented, but they are only necessary because automobiles are the sixth leading cause of death in most developed countries.
Then there are the obvious hazards found in modern industrial places of employment where chemicals, heavy equipment and other dangerous activities cause many to loose life or limb. Some times in the case of a person working with hazardous materials like asbestos or carcinogenic petrol chemicals it takes years for the affects to manifest themselves. Other times its instant death or dismemberment such as in the case of oil rig operators and electric linemen.
Finally there is war which has been made exponentially more deadly by the invention of nuclear, chemical and biological weapons and there oh so efficient delivery systems. Man has always put great effort into finding more effective ways of killing his neighbor. Now. however, he has the ability to kill all his neighbors.
Heath (Sick) Care
Advances in medicine, particularly over the last 100 years, are nothing less than awe inspiring. What used to be a death sentence is now often a simple trip to the pharmacy for antibiotics or an out patient surgery. Our knowledge of how the body works and how we can tweak it to cure disease or repair damage saves and improves lives.
There are some blunders in modern medicine too be sure. Things like drug interactions, blood transfusions, or deadly cures like chemotherapy. Also the general dependency on drugs and the focus on treating of symptoms rather than finding the root of the problem and curing it. Of course It could be argued that these are problems that arise from human nature and attitude rather than technology, so I think maybe this is one area where technology helps more than it hurts.
So, as I usually find to be the case, technology giveth but it taketh even more. I much prefer a quiet life free of frankenfoods, dangerous jobs and weapons of mass destruction to a modern life of deadly convenience.
