First look at the data.

Remember the cause of at least 4 blue zones was bad data. Pension fraud in Italy, record loss in Okinawa etc.

that's interesting. how did you find that?

Hi from Argentina! I think we have a very similar system. 110 years ago men got their national ID number at 18 (during conscription) and women didn't have a register until 30 year later (~1940).

(And when women got it, many lied to appear to be younger, like my gran-grandma that drop 4 years.)

So, expect a lot of unreliable data.

interesting! hi!
