Very few students ever become neurosurgeons or tree surgeons.

So clearly we should stop teaching children about the biology of the nervous system and botany.

There is nothing wrong with walking around and not knowing how trees work. There is nothing wrong with walking around and not knowing anything about nerve conduction or about how a reflex works.

Indeed, what needs to happen helpfully in our public school system is for columnists who have singled out botany and the nervous system as yawning time-wasters, what needs to happen is those columnists need to lead a front-page crusade against those disciplines.

It is a helpful contribution to our schools and our children's future.
