Stefany Anne Golberg tries to understand a rapidly aging planet, by looking to literature and beyond:

The number of people who are 60 and older is set to triple in the next 40 years. By 2050, there will be more people aged 65 and older than children under 14 for the first time in history. By 2150, one in three people will be over 65. In developed countries, aging is coming sooner than that. By 2050, half of the people in Spain will be 55 or older. In England, there are already more baby boomers than teenagers. In Japan, the world’s oldest country, more than 21 percent of the population is over 65. The world is getting older and the process, given current trends, cannot be reversed. There may never again be a world that is mostly young. ...

And yet, we haven't really asked ourselves just what it will feel like to live in an old world. Will reminiscing replace love songs? Will wisdom replace surprise?
