The NY Times had an article about a German program which teaches children how to safely start fires.
"Mr. Karawahn’s workshops aim to prevent tragedies caused by children playing with fire in secret. Young children who make a fire alone often won’t tell adults for fear of punishment. Even worse, they sometimes hide after setting a fire and end up dying from smoke inhalation."
I suspect teaching about it
Has to be sound.
No culture living without it
Has ever been found.
