humans are funny... always coming up with explanations for things. do we understand how a thing works? of course we do, just make up some explanation! :)

oddly enough, the researchers sound perplexed by this finding... but it makes perfect sense for animals to evolve reward-seeking behavior when the natural toxins are benefiting them
that's odd... i was just reading about how practiced tibetan monks have vastly increased gamma wave activity (an indication of attention). from the page: "If there's excessive attention, it somehow creates mental fixation," he notes.

a really excellent article speculating about the origins of morality... and its effects. from the article: "In a large Web survey, Haidt found that liberals put a lopsided moral weight on harm and fairness while playing down group loyalty, authority and purity.

What could be the social and sexual implications of this on one's perception of the smell of fellow humans?"
