I could have written the exact same thing.
And that empirical fact has served me well in my life as a young man, a parent and now an old geezer with stage 3/4 emphysema.
ALL my troubles are either my own fault or the result of a weakening immuno system.
I could have written the exact same thing.
I'm a skeptic. Pure and simple.
And any time when a "scientist" starts cooking the books, my skepticism rises dramatically.
When they aren't willing to discuss (or study) something, then science turns into religion and "consensus" turns into dogma.
And my religion is Catholicism, not pantheistic humanism.
And in my religion, before something is declared a dogma, it goes through a very, very rigorous and exacting process before it is accepted as an axiom (dogma).
It's an amazing thing that my religion has higher standards of scientific rigor than the "science" we see behind vaccinations and the "science" we see behind anthropogenic climate change.
