Eskimos don't actually 'kiss'by rubbing noses
Eskimos don't actually rub noses. But Canadian Inuits, as well as New Zealand's Maori people, do use their noses similarly to the way we use our lips: They sniff a loved one's face hard enough to suction the skin between their nose and upper lip. Though there isn't enough research to say whether this practice (or licking, sucking or blowing on a lover's face) produces the same feel-good chemicals as kissing, It's fair to say that we're doing them for same reasons. People seem to need to do [them] to connect with someone.
