There are so many people we can't get to. Sad but true. Many are very close minded to alternative treatments, I know this as I have enough older friends that I TRY. My mother was very open to all my suggestions over the years after I got into alternatives.

Your friend is probably very deficient in Vit D....and the doctors, don't get me started.

Does he have children you can talk to...otherwise not much you can do. I guess.
