The old hump could still emerge, however. Because the new study provides a simple snapshot of unhappiness by age at a single point in time., it is possible that today' s miserable 20-somethings will follow their predecessors' path and become even gloomier in middle age. It's not inconceivable that if young people start out this badly, they could be even worse off in mid-life," said Dr Bryson.
不过，原有的"驼峰"模式仍有可能重新出现，由于这项新研究只是对不同年龄段的不快乐状况进行了某一时间点上的快照式观察，因此今天饱受痛苦的二十多岁的年轻人未来也可能像前人一样，在中年时变得郁郁寡欢，Bryson博士讲到"完全有可能，如果年轻人一开始就这么糟糕，中年时期会更加不堪。"
