USA - Amtrak ride ‘like a box of chocolates’

...................When the two women sitting across from me found out I worked at a newspaper, they wondered if I was interested in investigating the potential dangers of fluoride in drinking water. (I graciously declined.) In their Northern Washington community, the town council had recently decided to fluoridate the water supply because fluoride has long been considered beneficial in preventing tooth decay.

But these women were adamant that their town consider a recent Scientific American article suggesting fluoride can be risky if it’s overused. It was food for thought.

Why just food for thought?
