It is good news! The life expectancy globally has increased from 62 years in 1980 to 72 years in 2015. This is as per the report of a United Nations Committee.
I remember that while I was studying in 1940s, it was told that the life expectancy in India was 30 years or so. It was mainly due to the large percentage of child death at the time of delivery.
India has also vastly improved the life expectancy since then. But much more is to be done.
