We're getting old but don't worry at least two United Nations divisions - UNFPA and UNDESAD - are looking into it.
Usually, this whole aging business is presented as a major looming crisis, requiring urgent action. In New Zealand, for example, concern about the ageing population, often referred to as a 'demographic time-bomb', explains the creation of both the New Zealand Superannuation Fund and the KiwiSaver regime.
But not everyone is so downbeat about the fate of an increasingly ancient world.
Even UNFPA tries to put a positive spin on the story, titling its introductory piece 'Population ageing: a celebration and a challenge'.
"Ageing is a triumph of development," the UNFPA intro says. "People are living longer because of better nutrition, sanitation, medical advances, health care, education and economic well-being."
Despite this, UNFPA admits an ageing population does pose one or two "social and economic challenges" before concluding: "Older persons need not be a burden".
