I have been reading with interest the comments made by Cem, D, and Chris in particular on "qualified" opinion as stated on the internet.
I know nothing about this subject, other than living 60 years and, as I stated before, 'surviving'on the diet of the 1950s and 1960s which was full of everything now condemned by the "exprts" and yet we are the generation set to live longer than any before.
I would also support Cem in one aspect at least; how experts can be 'persuaded' by financial incentives as to how they express their findings. That is due to me remembering the time when highly qualified scientists and other 'experts' we're stating smoking was very BENIFICIAL to one's health!! They stated a good smoke did your health no harm at all!!

The tobacco giants were pulling the strings, and big companies still do!
