I know just one person over 100 with an actual birth certificate.
Across U.S. states, the total and per capita numbers of supercentenarians dramatically decline right after the introduction of birth certificates (blue line).
Also, have you ever noticed that supercentenarians are more common in areas with more crime, more poverty, and lower average life expectancies?
Here's data for England:
The same pattern of supercentenarian numbers being correlated with poverty holds in (A, D) England, (B, E) France, and (C, F) Japan.
Across countries, you just see the same things over and over, from age heaping to weird correlations, so the conclusion is clear:
Supercentenarian numbers are driven less by regionally exceptional longevity and more by people defrauding pension systems and making up their ages.
Oh, and if you wanted to learn how to live a long life from the "blue zones" in Sardinia, Okinawa, and Icaria, good luck. Those places have low life expectancies and literacy levels, high crime, and lots of poverty.
Their long-lived people are not able to validate their ages.
This also applies to Loma Linda (not all that exceptional of a place).
In fact, across the whole U.S., at least 17% of centenarians were found to be non-centenarians in 2019 when someone just read through two plain-text files and found dates didn't match.
And this also applies to Nicoya, which is riddled with fraudulent ages:
If someone says they know someone super old, ask them: Where were they born? If it's in some place that was poor in the not-too-distant past, then they probably have the wrong age.
Wolf packs are remarkably good at respecting each other's established borders.
The project this data is from sometimes releases videos of how this plays out.
For example, here's a video of this playing out for a few wolves over a single day in Spring.
Alternatively, about 10-20% of wolf populations lack a pack. They're "lone wolves" and they're more likely to just wander across the territory of different packs
But this isn't permanent! Apparently this one eventually joined a pack and changed his long-distance traveling habit!
The story of peanut allergy is entering its final chapter.
Nowadays, we are beating back both peanut and other food allergies, and all it took was telling parents the right thing to do🧵
The story begins in 2000, when the American Academy of Pediatrics decided to issue some simple advice to parents: Have your kids avoid peanuts early in life. Don't expose them until they're at least three!
Parents complied. It turns out, they do that. They just follow advice from professional associations that appear to have authority.
So peanut allergy rates rose, from 0.4% in 1997 to 1.4% in 2008, to 2% in 2015.
But if the advice was right, the opposite should've happened!
