What would cause the average of women living in Japan to drop by 2.4 years (a slight exaggeration to be sure)?

The death of Japan’s oldest woman might cause the sudden decline, no?

Kaku Yamanaka was Japan’s oldest woman until yesterday. She was born on December 11th, 1894. She died at the age of 113.

There’s a reason why Japanese women on average are the longest living in the world. Can you say ‘Thank you, Yamanaka-san?”

Yamanaka was replaced by a young lady of 112 in Okinawa as the now longest living female in the country.

112-years old!! I remember not long ago there was Kin-san and Gin-san, a pair of Japanese twins born two years before Yamaka, who both lived to be more than 100 years old.

So, what’s the secret to living so long, we wonder?

Well, it’s not getting help from their husbands with daily chores. That’s for sure.
