More on OrpanCrow's post;
In 1800 the health conditions of our ancestors were such that about 43% of the world's newborns died before their 5th birthday. In 2015 child mortality was 4.3% - 10 fold lower than 2 centuries ago. In the year 1850 the average life expectancy at birth in the US was 40.5 for white females and 32.4 for non-white males, with an average life expectancy at birth of between 30 and 40.
Many years before antibiotics and advancements in health care arrived, the average life expectancy in the US and around the world dramatically increased. Why? Science. Scientists dissevered that treating water with chorine made it safe to drink . We take this for granted now, but circa 1900 this was a dramatic assertion that took years of convincing before it was widely adopted. Disinfecting drinking water and waste water was the single most important steps the world took to increase life expectancies, followed soon by antibiotics, vaccines and other advancements in the health industry. Again, science.
You AOWMs likely owe your lives to the titans who came before you, the scientists and researchers whose primary missions were to make the world a better place.
Overwhelmingly the cause for shortened life spans and those lived out in poor health in the year 2017 are due to lifestyle choices. Obesity, lack of exercise, drug abuse - smoking, drinking, meth, etc., and the crap so many of our species feels compelled to repeatedly stuff their every growing fat faces with.
It disgusts me when those with little to no education beyond HS, no experience or real knowledge about scientific issues arrogantly make definitive certitudes and platitudes about the evils and deficiencies of something they essentially know nothing about.
Show some humility. Or better yet, get yourselves to Google scholar or some other scholarly resource and understand what you are spewing nonsense about. I doubt that any of you AOWM have had a research class, been taught the empirical scientific method and how to develop a scientifically sound study or even read a published study on a topic, conducted by people who have devoted their lives to understanding.
What you are doing is called leveling, and it really doesn't bring these titans down to your levels. You just think it does.
