Well, you're not really correct on that one, as the life expectancy has gone down over the last few years. However, using 1900 for your basis saw a time when there were a great number of deaths due to the spanish flu. Life expectancy isn't what I was talking about. While living longer is true, it's not because of the pharmaceuticals , but more of healthier living, eating better, better working conditions and some early on drugs and vaccines, just nothing in the last 30 years has been that great.
Here's one I do know about. 1970s, if your A1C was higher than 149, you needed to start monitoring yourself once a month or so.... or come into the doctor's office every 3 months. Back then, almost all doctors allowed you to reach 200, before they started looking into it..... nad some doctors still feel that way. But not big pharma. Late 1980's they moved it to 130. Late 1990's, they had it to 125, then 120 and now it''s 110. However, if you are down around 80, you're considered hypoglycemic. So you can only be between 80 and 100 or you're labeled and those drugs are super super expensive. Now, this is the kicker, while those healthy people are taking drugs, they are weakening their pancreas for insulin problems down the road. So, for maybe 20 or 30 years, you are taking medicine for something which was not even recognized a few years ago as being bad for you. I am taking literally 10's of thousands of dollars of drugs for nothing, just til one day, I might need them. Are my numbers high, yes, but not drastically high, even without the medicine. Granted, there are those who need these medicines for diabetes, but to become a statistic, is just ridiculous.
