He also doesn't look very natty for a guy in his late 40s or early 50s.
That's why I was prepared to hate him just upon seeing the teaser image on the video. I am not especially thrilled by the info he is giving out, but I still like his attitude, so call it a wash. Too many of the guys promoting sound science are also complete *** when it comes to how to talk to and motivate people.
Some day a truly knowledgeable and charismatic creature will arise, but probably not. Knowledge seems to breed arrogance whereas ignorance cultivates charisma (to hide the lack of knowledge, y'see).
