I took your advice and didn't read, Kitty -- that said - I would do a lot of research on that first, [although I don't know what I'm talking about] but up to this point you have remained healthy -- which is what is most important above all else -- in a general sense all operations are unnatural - done by physicaI necessity only -- I'm not convinced the risk worth it, unless 99.9 % of others have been completely happy with the procedure -- and not just saying it [and secretly wishing they didn't - for some health reason] - but as I say I have no clue!
