Interesting research has shown that when a woman is in love, she still pays the same attention to the body odours of her beau and her female friends... but doesn't notice the smells of male friends or strange men. This suggests that once she has made her mind up, she switches off to other men. Is this for practical reasons, to stop her life becoming too complicated? Whatever the reason, it's nice.
