Genes key in compulsive urge to hoard

More hardwiring.

"People who have a compulsive urge to collect and clutter their homes with junk can partly attribute their problem to genes, a new study confirms.

In a twin study, researchers found that genetic predisposition explained a large amount of the risk for compulsive hoarding -- a mental health problem in which people have an overwhelming desire to accumulate items normally considered useless, like old newspapers or junk mail.

Of the more than 5,000 twins in the study, roughly 2 percent showed symptoms of compulsive hoarding. And genes appeared to account for half of the variance in risk."

Add this to the list together with:

hating mothers-in-law
psychopathic behavior
obesity
pedophilia
cocaine abuse
snake fear
fat women

and also add it to the list of useless research crap.
