Lots of key words in those sentences! When you say it like that it seems no different than the food and water we need too.

Well, I would say that it is as important as food and water. What happens is that most people in their hectic lives do not give importance, until they get sick and must recognize that they need more contact with nature. Thanks for sharing that interesting topic.

G-d forbid it should go that far...

Yw, and thanks for commenting too.
