第七章Today in the United States there are 72,000 centenarians. 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 Vaupel and his co-researchers, 50% of babies born in the US in 2007 have a life expectancy of 104 or more.1. By the fifties of the 21 century, there will be over 10,000,000 centenarians. ( )
答案:错
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, 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.2.“70 is the new 60”or “40 the new 30”indicates that we’re living younger for longer. ( )But the changes go further than that. Take, for instance, the age at which people make commitments 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, that milestone had shifted to age 29.3.It can inferred that people tend to postpone marriage in the United States. ( )Longevity also pushes back the age of retirement, and not only for financial reason. Yes, unless people are 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 80. But even if people are able to economically support a retirement at 65, over thirty years of potential inactivity is harmful to cognitive and emotional vitality. Many people may simply not want to do it.4.On account of economic reason, retirement have to be delayed with the increasing number of centenarians.( )
答案:错
And yet that does not mean that simply extending our career is appealing. Just lengthening that second stage of full-time work work may secure the financial assets needed for a 100-year life, but such persistent work will inevitably exhaust precious intangible assets such as productive skills, vitality, happiness, and friendship.The same is true for education. It is impossible that a single shot of education, administered in childhood and early adulthood, will be to support a sustained, 60--year career. If you factor in the projected rates of technological change, either your skills will become unnecessary, or your industry outdated. That means that everyone will, at some point in their life, have to make a number of major reinvestments in their skills.5. Because of longer lifespan, knowledge updating is needed. ( )
