"Never invest so much in anyone romantically that you lose your head, The Buddha of casual sex,I remain detached at all cost..."

"While lust and attraction are pretty much exclusive to romantic entanglements, attachment mediates friendships, parent-infant bonding, social cordiality, and many other intimacies as well. The two primary hormones here appear to be oxytocin and vasopressin (Figure 1)."
