She has a fantastic doctor who helps to 'look out for her best interest'. Since you obviously have no clue about her 'health' I don't think you should be concerned. Besides, they aren't as stupid as you seem to suggest. They look after each and every family members health and well being.
Wouldn't you be a little concerned if someone said the same thing about your family as if you weren't looking after their health? As if that would be anyone's business but yours.
I did not say they were stupid. I believe they are misguided, but, as I said before, that is my opinion.
This family invites public discussion of their lifestyle by being on television. It comes with the territory.
