According to Dr. Frank Lawlis in his book The IQ Answer, falling in love stimulates your brain. “The act of loving someone can be directly observed through the brain and throughout your body. Your immune system sparkles with excitement that creates a better defense against disease, and you actually gain muscular strength. Your creativity soars from the stimulation of the right brain so that even males begin to integrate their intellectual vision with creativity.” He notes that the type of love doesn’t matter as much as the depth of feeling. “We know that newborn babies thrive when loved, while those without love tend to suffer in mental strengths. . . . [Evidence indicates that those who love the most gain the greatest benefit cognitively.” Research has shown that falling in love raises levels of nerve growth for a sustained period of time, perhaps as long as a year. The hormones produced apparently help to restore the nervous system and trigger new growth.
