See, having studied a little psychology and understanding that "love" is basically a chemical reaction in the brain that is attached to our survival and procreational instincts, I really have to wonder. Or, are we getting love confused with our primal urge to procreate - an urge, that I might add, that has outlived it's usefulness. The world is sufficiently populated, after all. I think, maybe even believe, that now we're in a new cycle of human development where we can find a partner for life; someone who stimulates us intellectually as well as physically. Perhaps that is love. There's no more urgency to just procreate. The human race will survive (unless we destroy ourselves, of course. That's a different discussion). Instead of being a key to survival, which is very broad, maybe love has become a quality of life thing more suited to the individual. Either way, it takes two to tango, and I think, similarly, it takes two to live.
Damn. I'm full of it tonight. Make your comments quick, 'cause I'm prob'ly gonna delete this entry tomorrow.
