Love is by far one of the most discussed, written, expressed and implicit feelings in the range of human emotions. The Beatles told us that “love is all you need”. Dr. Theodor Geisel, better known by his pseudonym Seuss, stated that “When you are in love you cannot fall asleep because reality is better than your dreams”. Douglas Adams gave us a blunt warning in his book The Hitchhiker's Guide to the Galaxy, stressing that, in terms of love, "avoid it if possible." With all the artists, poets, writers, philosophers, scientists and thinkers in the world offering us contrasting and equally significant visions of love, is it really possible to explain it? Love is loosely defined as "strong affection for another arising from kinship or personal ties" and, indeed, there are aspects of this complex emotion that can be identified and discussed on all three levels of psychological analysis, from cognition to physiology to sociocultural. aspects of love. Biologically, love stimulates a plethora of neurotransmitters and hormones that, when all present at once, can explain the sensations of passionate love. Passionate love can be divided into two components: attachment and sexual attraction. The attachment between lovers has been compared to that which develops between a child and a parent, presumably functioning according to the same basic pattern. The neurotransmitters responsible for sexual attraction are adrenaline, serotonin and dopamine. Adrenaline is responsible for the effects of the initial stages of falling in love, such as sweating, inability to breathe, rapid heartbeat and dry mouth. Dopamine, a chemical that stimulates desire and reward, is also active, initiating an intense flow of pleasure towards the center of the card, which places value on the emotions and well-being of the individual, compared to a collective society that values ​​the group. In an individualistic society, love tended to be a substantially more considered factor in marital decisions. Along with these findings, studies have also shown that love tends to be more valued in societies with a higher economic standard of living, as well as higher marriage and divorce rates. Various studies have also shown higher rates of romance across different cultures. For example, Simmons, Vom Volke, & Shimizu, 1986, found that Europeans tend to have more romantic ideals than Americans. They also found that the American subjects had higher scores on romance than the Japanese subjects. Another study of North American and Chinese participants showed that Chinese subjects ranked higher in practical love and possessive love than North Americans.
