These days my mind is completely devoted to this issue.<p>I have came to the conclusion a smart person, is smart no matter whatever he/she is doing (of course after passing learning threshold).<p>It is kinda obvious if you don't think about it deeply, but when you think about deeply you can understand there is something about he or she which makes him or her smart.
I mean take gaming and mathematics for example, a number one and smart gamer if can pass threshold of learning mathematics, my estimation is how much good he she was good at gaming, he or she will be good that much in mathematics too (yes the scales).<p>I don't know how to express myself clearly.
