That's why I was asking for personal accounts. Many studies are biased and/or funded by others with economic interests. Many studies are pure lies or incompetence or nuts. There is a study contained in the NIH library done by a Chinese research organization I believe that concluded that tea can, or may. prevent and cure Covid-19! Good grief! No wonder the NIH has a disclaimer.

There is one case that I know of where a worldwide industry was propagandized for political purposes - to get the masses to believe something they wanted, true or not. Thankfully I believe the world is getting smarter and smarter, even though it may not seem like it at times.

The English writer I referenced was not, I believe, a doctor, but a famous or prominent observer of mankind. Often these kinds of people get things right, that's why they are famous. I believe there may be something to what was said about tea.
