If this a real article...
All these people have high functioning obsessive-compulsive personality disorders. Not 100% sure, but the behaviors are extremely typical of OCPD (which is different from OCD, btw)
50% of their mental energy is spent on things make a 5% improvement in their lives (this is one the things that screams OCPD).
Also, you will note, that none of them have children. Children are tiny hurricanes of chaos that force you to get rid of the excess crap, and focus on the things that actually make a difference. Either their weird genes will die with them, or they will eventually be forced to quit majoring in minors.
This coming from someone who has a similar personality type; I pride myself on being consistent and efficient with health related stuff, while also trying to keep from getting pulled into the "perfection trap". If you read the article, you know what a perfection trap is. I have heard of everything they mention in that article, and have tried a fair amount of it. Most of it's garbage, with the exception of eating real food, exercising, and approaching mental health with the same seriousness we approach physical health (which, as it turns out, responds really well to eating real food and exercising).
+1 to
@Bret S. and what he said about fragility. When the ICBMs start flying, they will be the first to go, as they try to figure out how to pack 6 months of coconut water into their Tesla.
