I am a bit puzzled. IIRC, the silicone in women's breast implants
would/could/did leak and cause fairly serious health problems. Yet, Dr.
Ornitz says "Silicone oils are excellent from a health standpoint" and
Mr. Smith says: "food grade".

Could anyone take a shot at explaining this apparent dichotomy?

Inquiring minds want to know.

A friend of mine, in the medical profession, once told me there is only
3 things she knew of which the body would "tolerate" as implant
materials: teflon/nylon, glass, and some grades of stainless steel ...

I don't know, but seems like diamond would be ok, doesn't it? Others
substances? Perhaps she was only speaking of the materials she has
seen, next time I see her, I will ask ... you have me curious now.
