A LOT of women love to shop, and buy things -- expensive things. But really it's not our fault! It's completely natural I swear. Of course like our bad mood swings, and our thirst for chocolate and cheese (not together), it's all linked to our monthly cycle. And now we can all blame a trip down Newbury Street, maxed credit cards in hand, on our bodies. At least that's what a new study coming out in Britain is saying anyway.
