Yesterday, I posted Eric Barker's article about being healthy. I appreciated his quote of Oxford professor Robin Dunbar:
What predicts whether you'll be alive one year after a heart attack? Pretty much two things: how many friends you have and whether you smoke. Oxford professor Robin Dunbar says, "You can eat as much as you like, you can slob about, you can drink as much alcohol as you like—the effect is very modest compared with these other two factors."
Evidently, according to Duckduckgo, Dunbar, an anthropologist, has predicted that a person can maintain close relations with about 150 people. This estimate has been dubbed "Dunbar's number".
