Normal Longevity increases of 1 year every five shows 100 year lifespans will become common amid calls to increase retirement to 70 in developed World by 2050
Since the 1950s, life expectancy has been increasing rapidly. On average, it has been increasing by one year, every five years. Babies born today in
2017 can expect to live to over 100, or in other words, they will live to see the year 2117.
The normally quoted life expectancy numbers are based upon the ages of people who are dying now aka people who were born 75-85 years ago. This is used as an estimate for the life expectancy of all people in spite of the trends towards longer lives.
This does not even account for extreme longevity advances using SENS and gene therapy.
The increase will be needed, as the number of people over 65 will more than triple to 2.1 billion by 2050.
By then, the number of workers per retiree will have halved to just four.
Michael Drexler, head of financial and infrastructure systems at the World Economic Forum, said the expected rise in longevity was the financial equivalent of climate change.
