Love
From Wikipedia, the free encyclopedia
Expressions of love may include the love for a “soul” or mind, the love of laws and organizations, love for a body, love for nature, love of food, love of money, love for learning, love of power, love of fame, love for the respect of others, etcetera. Different people place varying degrees of importance on the kinds of love they receive. According to many philosophers, the only goal of life is to be happy. And there is only one happiness in life: to love and be loved. Love is essentially an abstract concept, much easier to experience than to explain.
Some feelings that are often associated with interpersonal love:

- Attachment: satisfying basic emotional needs

- Emotional intimacy: sharing emotions and feelings
- Friendship: the spirit between friends
- Kinship: family bonds
- Passion: whole-hearted desire
- Physical intimacy: sharing of intimate personal space
- Self-interest: desiring rewards
- Service: desire to help
Lust is the initial passionate sexual desire that promotes mating, and involves the increased release of chemicals such as testosterone and estrogen. These effects rarely last more than a few weeks or months. Attraction is the more individualized and romantic desire for a specific candidate for mating, which develops out of lust as commitment to an individual mate forms. Recent studies in neuroscience have indicated that as people fall in love, the brain consistently releases a certain set of chemicals, including pheromones, dopamine, norepinephrine, and serotonin, which act similar to amphetamines, stimulating the brain’s pleasure center and leading to side-effects such as an increased heart rate, loss of appetite and sleep, and an intense feeling of excitement. Research has indicated that this stage generally lasts from one and a half to three years.[4]
Since the lust and attraction stages are both considered temporary, a third stage is needed to account for long-term relationships. Attachment is the bonding which promotes relationships that last for many years, and even decades. Attachment is generally based on commitments such as marriage and children, or on mutual friendship based on things like shared interests. It has been linked to higher levels of the chemicals oxytocin and vasopressin than short-term relationships have.[4]
In 2005, Italian scientists at Pavia University found that a protein molecule known as the nerve growth factor (NGF) has high levels when people first fall in love, but these levels return to as they were after one year. Specifically, four neurotrophin levels, i.e. NGF, BDNF, NT-3, and NT-4, of 58 subjects who had recently fallen in love were compared with levels in a control group who were either single or already engaged in a long-term relationship. The results showed that NGF levels were significantly higher in the subjects in love than as compared to either of the control groups.[5]
