I owe my continued good health to my avoidance of doctors and hospitals. I suspect, but only suspect, that some connection to early deaths and medical treatment might be there, certainly as I am reminded of the pneumonia epidemic of ten to twenty years ago when anyone over 60 went into hospitals only to contract the illness there, leaving hospital in a stiffer condition than they entered. I am reminded that the ancient Greeks, or at least the famous ones, lived long lives supported by very healthy diets.
Modern medicine is an industry, directly connected to economies. Perhaps in mass societies they are seen as necessary, but to what degree?
