this study was overviewed on the evening news. the claim was that women are happier when they are attaining maternal success at a young age and men are happier when they achieve material wealth at an older age. when i saw this on the evening news some man actually said that the reason women are less happy as they get older is because "their hormones get all whacky". http://abcnews.go.com/Health/story?id=5479994&page=1 shay
