A few months ago 60 minutes had an article on silicone cosmetic surgery.
Apparrently, many (so-called) doctors were basically taking a syringe full
of the (automotive) clear silicone RTV and injecting it directly into their

silicone after side effects showed up a few years later, and were left with
permanent scarring. I digress from brewing, so I'll shut up...
