love

and speaking of......love. One of the greatest predictors of love is proximity. Physical closeness leads to increased emotion, and it is not unusual to hear stories of bosses falling in love with their secretaries. On the other hand, scientists now think that at a critical time in childhood (sometime between ages 4-6), boys and girls who live in close proximity lose their ability to fall in love with each other, perhaps preventing the destructive act of mixing one's DNA with close kin.
