> Also, in the interviews I have seen of him, his blinking frequency is quite high, presumably because he is so low in body fat that his lacrimal ducts cannot manufacture the lipid portion of tear fluid properly.

Bryan Johnson is one weird dude and I would bet against his regimen's effectiveness. But stuff like this is just silly and makes me doubt the rest of this post.

Are you an MD like the author? And even if not - what is your rebuttal here?

I'm not an MD. Jumping from "he blinks a lot in interviews" to "his lacrimal ducts cannot manufacture the lipid portion of tear fluid" is silly. It's like something from a TV show doctor. He's being interviewed and some people blink a lot when they're nervous!

We're talking about a guy that chooses to be in front of a camera, weekly, for millions of views.

It isn't so straight forward.

Van Morrison is a world famous musician who has performed on stages since the 1960s. When he last visited my city about a decade ago he played for nearly the entire duration of the show with his back to the crowd as a way of minimizing the performance anxiety that he felt.

The lacrimal duct doesn't produce the tear film lipids, it's the meibomian gland. Also I think he meant the lacrimal gland, not the duct, but that'd still be incorrect.
