A baby born in the west today will more likely than not live to be 105, write Lynda Gratton and Andrew Scott of London Business School in their crucial new book, The 100-Year Life. That may sound like science fiction. In fact, it’s only cautiously optimistic. It’s what will happen if life expectancy continues to rise by two to three years a decade, its rate of the past two centuries. Some scientific optimists project steeper rises to come.
If turning 100 becomes normal, then the authors predict “a fundamental redesign of life”. This book shows what that might look like.
We currently live what Gratton and Scott call “the three-stage life”: education, career, then retirement. That will change. The book calculates that if today’s children want to retire on liveable pensions, they will need to work until about age 80. That would be a return to the past: in 1880, nearly half of 80-year-old Americans did some kind of work.
