Young adults in more developed countries can expect to celebrate their 85th, 90th and even their 100th birthdays. Although time horizons have a major influence on behavior and adult development, little is currently known about how young people feel about the prospect of living such long lives. We therefore explored young adults’ preferred life expectancy (how long one wants to live) based on questionnaire data from N = 715 university students in Austria, Norway, Poland and Russia. The countries represented in the sample differ substantially with regard to period life expectancy and the extent to which women outlive men. Overall, participants indicated wanting to live for M = 87.43 years (SD = 14.91), M = 8.12 years longer than they expect to live and M = 13.04 years longer than they think that an average person with the same age and sex will live. There was thus no indication that participants felt that they will live “too long.” There was a 7-year difference between the country subsamples with the highest and lowest PLE, providing first evidence that PLE meaningfully differs across countries. Men wanted to live longer than women in each country subsample. Despite country differences in the extent to which women outlive men, there was no evidence that the magnitude of the gender difference in PLE differed across country subsamples. PLE was also related to young people’s representations of old age and subjective health. Young people who prefer to die relatively young (< 80 years) were much more likely to use tobacco daily and be physically inactive than their peers.

寿命太长或快死了？探索四个国家的年轻成人大学生想住多长时间

较发达国家的年轻人可以期望庆祝自己的85岁，90岁甚至100岁生日。尽管时间跨度对行为和成人发展有重大影响，但目前对于年轻人对如此长寿前景的看法知之甚少。因此，我们根据来自奥地利，挪威，波兰和俄罗斯的N  = 715名大学生的问卷调查数据，探索了年轻人的首选预期寿命（人们希望活多久）。样本中所代表的国家在预期寿命和女性比男性长寿方面有很大差异。总体而言，参与者表示希望生活M  = 87.43年（SD = 14.91），M =8.12年的时间比他们的预期寿命和中号 =比他们认为平均年龄和性别的普通人能够生存的时间长13.04年。因此，没有迹象表明参与者感到自己会“过长”。PLE最高和最低的国家子样本之间存在7年的差异，这提供了PLE在各个国家之间存在显着差异的第一个证据。在每个国家/地区的子样本中，男性都希望比女性寿命更长。尽管国家对女性的影响程度超过男性，但没有证据表明PLE的性别差异在各个国家的子样本中都不同。PLE也与年轻人对老年和主观健康的表征有关。相对于同龄人而言，更愿意死于相对年轻（<80岁）的年轻人每天更可能使用烟草且身体不活跃。
