As far as I know, phero

is sensed by human\'s VNO unconsciously . Imaging there are two guys, A and B, standing close to a girl. A has

phero on his body, B has nothing. If the girl is attracted by the phero, is it possible for her VNO to \'tell\'

her that phero is from A?

I\'m thinking about this question because in a crowded environment, e.g. bus, night

club, if I\'m wearing phero, how could other people know the phero is from me but not some other guys?
