Tony,
Glad to hear it’s nothing worse and hope you find the problem soon.
I browsed the article. He’s very vague and presumptious: the body prevents increase of blood flow to the brain? The brain prevents increased blood flow?" What does that? How? “Gravity has no effect? Does not cause changes in posture? Chi or prana is like electricity?”
There’s no substance in what he’s saying. It’s another case of self-validation through the internet. Let him go.
