'Elderly population Exploding globally'

The number of people globally aged 65 and over is expected to more than double by 2050 as the world's senior population continues to rocket, a US study said Monday. The global population is aging at an unprecedented rate with 8.5 percent of people worldwide -- or more than 600 million -- now aged 65 and over, said the US Census Bureau report. By 2050, global life expectancy at birth is projected to increase by almost eight years, from 68.6 years in 2015 to 76.2 years, the study said.
