Hello anonymous@19597 ,Severe starvation does cause genetic damage and has been used by occupation troops and governments as a gift to be passed to future generations. It would be unfair for me to say the idiot symptom is definatly inbreeding. In u.s. south, after the civil war, it was likely a union government policy of food control.Are we not lucky? Wierd southerners depicted in parts of that movie.Almost Hollywood typical.
