By chance I came across these talks on YouTube from a chap called John Bergman - I believe he a Chiropractor and has uploaded over 300 health videos on his channel
www.youtube.com/user/johnbchiro
He also has some unique insights - as he says in one of his videos that he was crossing the road and got hit by a car and broke both his legs - so he knows about healing from the patients point of view.
In particular I've enjoyed his videos on Autoimmune Disease and Arthritis
He's go so many talks on so many subjects - that I can't believe he's not got subscribers in the 50,0000+ range
If you think what he has to say is useful then I recommend letting other know about this guy
