Commenting has become my newest semi-retirement hobby.  
Sapolsky’s ability to do the science, practice the art, talk out both sides of his mouth is the living proof of life.  
The more public / popular a person is at any given moment in time, cannot speak in pure honesty, it is always nuanced to that moment.  
It seems to always be that way. Even in war.
Sapolsky is not running for public office, which is a 50/50 popularity contest, not just an intelligence contest. 
I enjoyed it immensely when he mentioned the words, “first world problem, …. he, being a pessimist, … obsessing over stress as career. 
He is so human and a pretty wise one.
