"Curiosity is the most wonderful human quality. It's the reason we've managed to double our life expectancy and venture into space. So if someone says they have a miracle cure and they'll sell it to you for fifty quid, shouldn't you be just a little bit curious as to the evidence behind that claim? It's not as if asking for that evidence before you hand over your hard earned cash is unreasonable."
