Lessee, I was studying blood chemistry and the construction of the brain and heart at age six, and have spent maybe a decade studying anatomy and medicine with shelves full of books yet you somehow conclude I know nothing about medicine? Interesting. Perhaps you need to get yourself a brain scan? You know-- to see if there is anything up there?
You shouldn't need to guess about things you are apparently expert in.

CONGRATULATIONS! You understand that surgeons go to medical school! I am IMPRESSED. There is still some hope for you. And yes, I sure do hope my surgeon knows more than me, a lot more, otherwise, I'd be operating on myself, idiot. Always fascinating how the bigger the twit you leftists are, the more you assume you know while thinking other people dumber. Go back to bed where you can do yourself the most good.
