But if elements are highly reactive, then their post-reaction compounds as a broad generalization will tend to be more stable. Fluoride for your teeth is a complicated story, but the stability of the incorporated fluoride mineral is essential.
Maybe life is how fire found a great new way to survive. Living things are all about collecting and using energy after all. We’re all burning in a sense.
The Master speaks:
When fire evolves a resistance to water, we’re all in trouble.
