Were you born with P.P. or was it something you acquired?
Is it as strong with people who acquire vrs. people who learn it.?
In college we used to play "stump the idiot savant" with this one guy who had PP, we would press down 11 keys on the piano at the same time and he would tell us which one we were'nt playing, he was right 100% of the time. Is this normal with people who have developed PP or was this just an extreme case?
