To be fair, you wouldn't really want this advice from an MD either (although they certainly would be much more qualified than a lawyer to give it). You'd want it from someone with a research doctorate (i.e. PhD) in medicine or some other related field.
Was about to link the post in the F1 thread, then realised it was also yourself that posted that!
Coincidentally, most media outlets have stopped adding the 'Dr.' before his name when reporting this story!
(His Doctorate is in Law, he's not an MD)
