Which begs the question, when people are willing to commit their children to this kind of super-intensive training regimen at such an early age, why on Earth are they doing it for games or music and not something (if you will excuse a crass way of saying it) <i>useful</i>?<p>Imagine a physicist or mathematician or engineer tutored in their discipline from age five!  And imagine if those were as <i>common</i> as the little kids one sees dutifully going to piano practice every afternoon.  The world would look very different.
