In the balance: silver tsunami or longevity dividend?

While still early in the 21st century, nations are experiencing an unprecedented rise in people living into their 80s, 90s, and even longer. Many national leaders view with alarm a possible tidal wave of chronic age‐related disease and disability. Competing scenarios predict insurmountable social and economic stress; or alternatively, a future in which older people continue to function and contribute during extended healthy years of life made possible by scientific and medical advances. The latter vision, termed the 'longevity dividend', is discussed in terms of strategies for achieving this goal.
