before the age of 21....i'd say none. never had a problem. i don't have pd, so i called my dad just now and asked him.

same answer for before 21.

any reason as to why you ask if before 21? you realize that some folks...and i WILL NOT name names....that age 21 was more than a few years ago?

i think i constipated my dad just asking him to think back that far.
