There is altogether too much emphasis put on length of life vs. quality of life. Drugs are highly over rated. Sure there are times (I'm getting tired of repeating this) when drugs are wonderful, necessary for the treatment of type 1 diabetes and high blood pressure, but it's much better if people can get away from their reliance on drugs if at all possible by altering life style. If the Gov't. put as much money into promoting healthy lifestyles as they do on inventing another new drug, the popuation as a whole would be much healthier at much lower expense. My MD. in Grand Forks told me that if all healthy Canadians across Canada simply walked for one hour a day, health care costs for the Country would eventually be reduced to half.
Even if all of this is true, you are simply describing how a good situation may be made better. but the fact is, very few (probably not even you) would want to go back to the good old days, with no antibiotics and communicable diseases (typhoid, small pox, cholera, malaria etc.) widespread. Back to the days of unsafe drinking water (no fluoridization), poor refrigeration etc.
Or maybe you would, may be you are of the hardy, frontier type who thinks that people have it too soft these days. But I wouldn't (and I suspect neither would most people).
