Although humans measure time using a continuous scale, certain numerical ages inspire greater self-reflection than others. Six studies show that adults undertake a search for existential meaning when they approach a new decade in age (e.g., at ages 29, 39, 49, etc.) or imagine entering a new epoch, which leads them to behave in ways that suggest an ongoing or failed search for meaning (e.g., by exercising more vigorously, seeking extramarital affairs, or choosing to end their lives).
尽管人类使用连续的尺度来衡量时间,但某些特定的数字年龄比其他年龄更能激发自我反思。六项研究表明,成年人在接近新的十年年龄(如29岁、39岁、49岁等)或想象进入新的时代时,会进行对生存意义的探寻,这导致他们以暗示正在进行或失败的意义探寻的方式行事(例如,更积极地锻炼、寻求婚外情或选择结束自己的生命)。
