Ok where is this study? As a psychologist student I'm very interested
Also an trisomy is not psychological, that'd be a biological study, unfortunately I dont think you know what half of those words even mean
Also, there are no fucking links whatsoever between any psychological disorders and fucking chromossomic disorders.
And to fucking top it all, being born with no legs has nothing to do with chromosomes, I think that part stands out as the most retarded in a rather retarded text
