Yes, plenty of them do know that stuff. But with those who do know that they like doing sport or practical things, or even stuff like being into music etc, schools tend to just ignore that.
Another I knew who realised that academic stuff didn?t interest him decided to give up on school well before it was legal for him to do that. I had some real reservations about that and so did his mother who was a high school teacher, his dad had died.
He did manage to do very well for himself indeed, basically doing all the media stuff for the most important golf tournaments etc.
But there aren't all that many people who can manage something like that.
