great logic. it has been proven impossible, therefore it is impossible. why just today i saw an article about how the sun prevents cancer, and now the entire dermatatology industry is going to have to eat crow for years for causing cancer by forcing their patients to wear sunblock. fairly stupid, but thankfully this is something that alternative medicine people have know for years. no news here, stay away from the skin doc, they are misinformed.
need i give you other examples? hormone replacement therapy, vioxx? anyone?
