He was talking a bit too fast for me, which I found irritating, but it was (overall) quite informative and bang-on for me. Amazing. It's interesting that when he was talking about the tertiary Ti he mentioned people looking as if they were'nt listening to you and going inside their heads. That's what I'm notorious for, apparently, which made me chuckle. I guess that's why I wished he would have talked more slowly. I needed to "process"!!
