Physical health is very complex, determined by genetics, diet and exercise, personal habits, exposure to toxins, mental and emotional stress, and many other factors. It is no business of mine whether you exercise, what your diet is, whether you drink or smoke, what your sexual activity is. Neither have you any right to micromanage my life. If you choose to trust the government and believe there is a deadly virus, that is your right, and if you want to be injected with God knows what, that is also your right. But we have a mass media that does everything in its power to corrupt people and encourage self-destructive behavior; for them to pretend they care about "public health" is beyond ridiculous. This is about control, and "public health" will be used to impose more and more severe restrictions until the people have had enough. Obviously this will be extended to mental health as well; we've even seen academics proposing to add psychoactive compounds to the water supply, in order to control behavior. One even suggested adding psilocybin, the active component in magic mushrooms, to the water supply.
