Very valuable, useful and coherently well reasoned opinion @practicalthought. I bet many people who read this post will find plenty of logic, powerful insight and soundly advice through your comment. :)

I see you've bothered and has taken your time to fiddle deeply across all the links and videos that I've presented on this post to digest these well and came back with a thought provoking exposition to encourage further the discussion. ¡Thanks for that mate!

Cheers!!
