I missed your reply. One of his videos is him talking about his life. He also designed homes and business buildings and they are quite impressive. I divide the population into two groups.
The first are what I call folks who have led a "cookie cutter" existence. You know, high school, then trades or university, work whatever trade or profession you chose, had a family, retired, then died.
The second group the non-cookie cutters lives are all over the place, first high school, then who knows how many trades/jobs/undertakings over the years, perhaps travelled all over, then retirement often with difference projects, then die.
This guy is definitely in the second category. I find the non-cookie cutters to be much more interesting to talk to as their experiences are so varied. By the way, he is a member here but I think he has posted only a couple of times.
