It's the old story of 'nature & nurture', isn't it Rob? (I've also alluded to this in Lizzie's education thread below the line).

We're all genetically different. I've often hesitated at the idea of genetic, inbuilt talent for anything, and I'm still not sure whether I subscribe to that idea totally. But I do believe that our brains work in very individual ways - a midwife friend once said to me that there was nothing as individual as a ward full of new-born babies!

But even so - practise until the day you die... and then some!
