To unleash productivity, innovation, and growth in the 21st century, we must realign discussions about the future of work to recognise the importance of aging and longevity – unprecedented, accelerating trends that are reshaping economies, societies and individual lives around the globe.

The world is getting older. Children born in the developed world today can anticipate living to 100 and beyond, and those of us arriving at old age in good health stand a very good chance of living into our 90s. These shifts will change the workplace environment, and also offer companies new economic opportunities.

Jim Michaels’s “When It Comes to Retirement, I’m with Cicero” (op-ed, Jan. 12) desperately needs a 21st-century reality check. Longevity reaching to 100 years is becoming more common.

Aging Today’s end-of-year 2018 In Focus section, “Global Aging and the Future of the World Community,” is prescient as it is the perfect set-up to 2019, which heralds the tipping point for the mega-trend of population aging.

Yannis Palaiologos’s “Greece’s Bailout Ends, but Prospects Still Grim” (op-ed, Aug. 20) doesn’t have to be prophesy if Greece continues the more profound change of aligning 20th century public policy and social and economic institutions to 21st century age demography.
