Grin-

I think that the words typical and PG are not meant to go together! LOL, every child IS a lovely puzzle. Think about it this way, if a PG kid is learning years ahead of age-mates, he can cover years worth of specialization or esoteric knowledge by the time he is eight or ten. Typical kids just don't have as much time to get into things, and they don't end up so far from where they started. The further they get from "start", the less likely it is that they will follow that well trodden center path that gets most of the traffic.
