7、r O） transmittedSection BHow Work Will Change When Most of Us Live to 100A.Today in the United States there are 72,000centenarians（百岁老人）.Worldwide, Probably 450,000. If current trends continue, then by 2050 there will be more than a million in the US alone. According to the work of Professor James V

8、aupel and his co-researchers, 50% of babies born in the US in 2007 have a life expectancy of 104 or more. Broadly the same holds for the UK, Germany, France, Italy and Canada, and for Japan 50% of 2007 babies can expect to live to 107.B.Understandably, there are concerns about what this means for pu

9、blic finances given the associated health and pension challenges. These challenges are real, and society urgently needs to address them. But it is also important to look at the wider picture of what happens when so many people live for 100 years. It is a mistake to simply equatelongevity（长寿） with is

10、sues of old age. Longer lives have implications for all of life, not just the end of it.C.Our view is that if many people are living for longer, and are healthier for longer, then this will result in an inevitable redesign of work and life. When people live longer, they are not only older for longer

11、, but also younger for longer. There is some truth in the saying that“70 is the new 60”or“40 the new 30.”If you age more slowly over a longer time period, then you are in some sense younger for longer.D.But the changes go further than that. Take, for instance, the age at which people make commitment

12、s such as buying a house, getting married, having children, or starting a career. These are all fundamental commitments that are now occurring later in life. In 1962, 50% of Americans were married by age 21. By 2014, thatmilestone（里程碑）had shifted to age 29.E.While there are numerous factors behind t

13、hese shifts, one factor is surely a growing realization for the young that they are going to live longer. Options are more valuable the longer they can be held. So if you believe you will live longer, then options become more valuable, and early commitment becomes less attractive. The result is that

14、 the commitments that previously characterized the beginning of adulthood are now being delayed, and new patterns of behavior and a new stage of life are emerging for those in their twenties.F.Longevity also pushes back the age of retirement, and not only for financial reasons. Yes, unless people ar

15、e prepared to save a lot more, our calculations suggest that if you are now in your mid-40s, then you are likely to work until your early 70s; and if you are in your early 20s, there is a real chance you will need to work until your late 70s or possibly even into your 80s. But even if people are able to economically support a retirement at 65, over thirty years of potential inactivity is harmful tocognitive（认知的） and emotional vitality. Many people may simply not want to do it.G.And yet that does not mean that simply extending our careers is appealing. Just
