Love me some Alda. His Scientific Frontiers show is well made and fun to watch. Good to see he's still kickin' it.
On one of my last camping trips, a buddy of mine brought up an interesting idea of fire when he said that it is a living thing. I had honestly never thought of it like that before but he's right. It is created, consumes oxygen, and eventually dies. And in order to keep it alive you have to feed it.
