  • Mystery or “the chase” is often a critical element in romantic love. Sometimes called the “Romeo and Juliet effect,” a situation with challenges or obstructions is likely to intensify one’s passion for a loved one.[6]
  • Scientists suggest that the advent of cooking led to healthier food which, in turn, led to bigger brains and an increased capacity to woo potential lovers with new forms of linguistic and artistic seductive flairs.[6]

Individuals are more likely to fall in love if they are looking for adventure, craving to leave home, lonely, displaced in a foreign country, passing into a new stage of life, or financially and psychologically ready to share themselves or start a family.[4]
  • Women around the world are more likely to fall in love with partners with ambition, education, wealth, respect, status, a sense of humor, and who are taller than they are.

As romantic love wanes, attachment love, a more stable love, sets in. To keep the passion alive, experts suggest doing satisfying and exciting activities as a couple.[6]
  • High levels of testosterone may suppress oxytocin and vasopressin (chemicals associated with attachment love), which may explain why men with higher testosterone levels tend to marry less often, be more abusive in their marriage, and divorce more. When a man holds a baby, his testosterone goes down, perhaps as a result of increased oxytocin and vasopressin.[3]
  • Women often feel loved when talking face to face with their partner; men, on the other hand, often feel emotionally close when they work, play, or talk side by side.[6]

  • Couples around the world who divorce tend to divorce around their fourth year of marriage. After four years, marriages generally stabilize until around eight years.[6]
  • Being in love increases levels of dopamine while a broken heart decreases levels of dopamine. To increase dopamine, rejected lovers should increase their dopamin levels by excercising and enjoy the sun. Smiling also activates nerve pathways that can create feelings of pleasure.[6]
  • 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.[6]
  • Kama Sutra (love + thread, rule) is an ancient text on love in Sanskrit literature written by Mallanaga Vatsyayana around the second century A.D. Kama is the Hindu god of love and also means desire. Sutra is a manual or a guide.[6]
