Survivorship bias.
2 comments

If we are measuring survival, surviving is not a bias, it's a data point

Without taking into account genes can you explain why Japan has 54 centenaries every 100k people, France 34, Italy 33 and US only 22?

Supercentenarians and the oldest-old are concentrated into regions with no birth certificates and short lifespans

Sardinia contains only 1/60 of Italian population.

The post you linked does not look very reliable

Moreover I'm not talking about super centenaries, but basic life expectancy

People who live more in general have probably better genes, we don't care how many die if we are counting those that survive longer than average

In US life expectancy is very low for being a developed country

And we can't really say that crime rate or frauds are higher in Okinawa than in Los Angeles

Nobody would believe that

Btw, what about France?

how so?
For every 1 person who lives an unhealthy lifestyle and lives a long time, there are untold millions who dont
Still in some countries many more get old than others

And I'm talking about countries with the same level of wealth (more or less)

Japan has 2.5 times more centenaries as a percentage of the population than US

well, you are right and i get what you are saying.

but in the current situation most people in that age range are dying. he survived.

isn't it worth talking about or giving it a thought?
