As with all these things I think they are talents. Something we just pick up easily and something no matter how hard we try we are never going to be better than passable at.
I enjoy playing the piano but no amount of practise is going to get me to concert pianist standard, but if i work at it I can play in a band! That is just sad reality there are limits on what our bodies can do.
That said I am less convinced that there are limits on what our minds can do so maybe we can teach ourselves to be Astor-physicists if we try hard enough.
