Huh. Well, that's not good. I still like what the author has put together here and think it may help some people. But perhaps he needs to rethink some of his other ideas.
Author sounds a bit obsessive about all things in life. It's appropriate for a doctor to tell their patient the facts about their situation. If laypersons do that they are going to run into social friction.
Doctors would face the same amount of social friction if they did what this guy is doing, which is giving his unsolicited opinion about the health of people he does not know personally, and has only seen pictures of online.
