just my opinion but if i were you john, i'd run this stuff by someone who actually does population epidemiology, especially on pd, before posting anything this wildly speculative and possibly unnecessarily worrying people. imho responsible scientists don't do this.

i could just bite my tongue but that's not me.

you think researchers somehow are ignoring looking into this possible correlation because you can't find any research? i think they would have seen it by now if there was one.
