Eisenhower warned against the military industrial complex; he might have done us a favour and added the 'industrial complex'. The latter represents the power and proclivity of industry to hijack and convert science to its own profitable ends. For a half century, the sugar industry, so-called scientists and unwitting medical practitioners perpetuated a hoax on the world. It convinced us that fat, not sugar, was the cause of heart disease. Millions cut dietary fat only to become fat, diabetic and prone to heart disease. 

I have huge sympathy for victims of melanoma. And yet it is inevitable that after industry has pocketed billions exploiting an irrational fear of the sun, real scientists will pronounce the whole thing a scam. Indeed they have already done so by declaring that genetics (phenotype) and repeated sunburn - not normal, sensible exposure to sun - are the real risk factors. Demonization of the sun has created a generation of draculas whose health has suffered needlessly.
