My initial reaction was, “It can’t be true!”. I’ve enough gray hair to know that if something sounds too good to be true, it’s normally an easy way to lose money. But this was one of my editors talking. And I’ve also got enough gray hair to know you don’t tell your editor he’s full of baloney. That’s a speedy way to get fired. So I politely listened. Particularly, since preserving healthy teeth has always been a good way to preserve your health.
