Prodigies, which can be a special group, exist in this world. I already heard some story about talented children. In China, there used to have a institute for cultivate gifted children, but the project failed because the aim focus too much on achieve academic goal thereby ignoring to activate some social ability of those young children. After graduated from that project,although they have high intelligence, the kids don't know how to chat with other people and take care of themselves. Therefore, they led a lonely life when they got old.
