Assess situations. Weigh the risks. Control.

People often say that love is from the heart. Metaphorically speaking, yes sure it does come from the veiny, cancer-causing organ, but in the scientific sense, this thing we see as love; attachment, longing, sexual urges - all of it are just a potent mix of chemicals your body brews out of boredom in a “Forever Alone” lifestyle.

Being a descendant of animals means we share the common goal of reproducing before rotting away. That’s probably the reason why old people without offspring tend to be more grumpy or just plain more evil. According to the last phase of of Erik Erikson’s Stages of Psychosocial Development (Ego vs. Despair), old people look back on their lives as a testament to how epic their life was. And if they had children.

Chemicals of Lurve 

1. Sexual Hormones

Testosterone and Estrogen are the two primary hormones concerned with our individual gender specifications. Testosterone is concerned with manly things. Estrogen for erm, well, feminine things. As we mature, our body starts to produce one of the vital fluids that we wish vampires also drink. Sperm is produced from the testes of the males, Egg cells for the ladies. Connection in love? When two couples decide to go and perform coitus, the moment that the sperm meets the egg, a spark of chem reactions spark out of the brain that makes you go “AAAHHHhhhHHuuuuuu” actually means, “I’m in love with you, darling!” The essence of lust comes from our hormones.

2. Dopamine

Ah yes, Dopamine. Dopamine is a hormone that gives you that fuzzy feeling of intense awesomeness after doing a particular goal. The harder the goal is, the higher dose of dopamine is secreted to the brain (e.g., standing up to get the remote). The same principle also applies to love. Dopamine secretion levels increase as you exert more effort (think studying for math 11 and actually ****ing passing) and you get the girl. Get no girl, you feel crappy because you get no dope, but then you play Call of Duty and realize it’s better than nothing.

3. Serotonin

Serotonin is the body’s happy drug, which prevents you from thinking of anything else. (But then you wonder why are there two timers.) When you are attached to someone, or at least have a crush on that person, serotonin is being the Alpha Male in your brain and bitch slapping other thoughts that are not related to the girl. Some people who take SSRIs (or SHIT, SEROTONIN RUNS IT as I like to call them) as medication for obsessive compulsive behavior (and also premature ejaculation. surprise surprise!), which allows the brain to produce more serotonin, are said to be less likely able to fall in love. 

4. Oxytocin

Oxytocin is the God of Hormones. Oxytocin is the primary hormone that constitutes orgasm, stimulation, orgasm, feeling of being a pair, erection, orgasm, and most of all, orgasm. HAIL OXYTOCIN!!

Intercourse increases the level of trust between the lovers, since orgasm allows the brain to produce more oxytocin, thus making unrequited and random sex still an option for romance.
