According to Bioideology, love is a necessary prerequisite to fulfill your moral obligation of extending your family line. Love is a function of hormone oxytocin. Oxytocin is a product of activities that include eye contact, hand-holding, sharing an emotional experience, hugging, dancing, cuddling, and sex. Using these techniques, one can develop love to almost any human being. People, who can't find love or maintain a relationship, simply do it wrong or do not try hard enough.
