I’d certainly salute you for having good genes more than anything else.
Medications sell because they more or less successfully address problems of less fortunate people. Most people can treat a cold or flu at home, but if it keeps up more than a week it’s wise to see a physician to rule out complications. If you get pink eye it’s better to get antibiotic drops than to risk going blind. Etc.
Sorry to say that you are wrong... but it is not uncommon. I have had relatives that went to the hospital and suffered the consequences (usually caught something other than their original disease), so no...I say thank you to hospitals.
Now I can understand that some of the common remedies work for diabetes, headache, and other common problems, but if you actually want to live longer - stay away from doctors and hospitals at all costs... You will catch more that you originally had... This is one of the major “Universal Health Care” problems that you will forsake for possible care otherwise....
