I thought the drug companies had love all figured out, fill up on dopamine, serotonin, and oxytocin and you'll walk around with hearts in your eyes. If I was a chemist like in the movies, I would cook up a batch of love by adding in about the same amount of dopamine found in pple with schizophrenia, equal amount of serotonin found in happy peeps or maybe brains that have been blessed with good maryjane, and the apparently secret ingredient, a handful of oxytocin. Oh and now, I guess you need this vasopressin hormone, seems like a good bro if its receptors help with the re-uptake of Oxytocin. Maybe it could help with other deficiencies in the brain associated with pple with autism and stuff. But autism seems cool when you see amazing austics with these incredible abilities that boggle the mind.
