You assume that everyone is as intelligent as yourself or enjoys having a thirst for knowledge. There is too much crap taught at schools, the whole of education is a mess.
He is right, students should be taught about food, more physical exercise, basic arithmetic without a calculator, how to conduct letters, emails, how to spell! They should be taught about finance how it all works in the real world.
No one needs to know about some war in the 1800's, or how rocks erode over time or what pi is. If you do, there's the internet at the touch of a button to explore. I could not stand history at school, it was boring, now you will find me watching all sorts of videos online about all kinds of events.
One thing i will never understand is that everyone has their own unique body, it will never leave you and you can never replace it and yet 99% of people would not know apart from the main organs what is inside their body or how it works.
How many people know what flu is? I would imagine most would say it's a virus you get in the winter that knocks you out for a few days. But how many know what actually happens and why? And how many know why the medicine we take and what's in it makes us better and recover from it? This is the stuff that should be taught in schools not half the crap that is currently on the curriculum.
