The average life expectancy for Japanese men is 80.5 years of age, while for women, life expectancy was calculated at 86.83 years of age, Fuji TV reported Friday.

The life expectancy in Swaziland is 49.4 years, while in Japan it is 82.6 years.

In the Bronze age, for example, life expectancy was 26 years, while in 2010, it was 67 years.
