A new study suggests that a woman's most intense relationship in her 20s is with a member of the opposite sex, but after the age of 45 this relationship shifts to a much younger female who is likely to be her daughter. The researchers suggest that women are more strategically driven than men in how they invest their time and after finding a mate, they shift their attention to grandchildren.
