A recent study found that life expectancy in 2040 is set to increase a little in all nations but that rankings will dramatically change. For example, Spain has now taken the top spot for a longer lifespan but China and the United States have switched places since last year.

The ranking mentioned is expected to drop to 2nd place in 20+ years, according to Saudi Gazette.
