I'm pretty skeptical that there are vertebrates that live 200+ years. All the longest living giant galapagos tortoises conk at ~150 years old and they all have very shady origin stories for how they got to the zoo.pic.twitter.com/eeFbEGpfVi

From the sharks paper (screenshot). "Von Bertalanffy" is a method to link age with size, as far as wiki says. Basically they used size to train a model which as been tested with sharks from post-WW2, as far as I understand. Seems a bit circular, after assuming size predicts agepic.twitter.com/iRszPV3B8d
(That said it's almost midnight, I know nothing about the topic, and I just quickly skimmed the paper on scihub out of mere curiosity, so I put a low confidence on the above, and would love to hear what others think.)
I haven't given much thought but I doubt their method yields an accurate result. At first, it seems stupid to figure this out, but then you realize that vertebrates are quite similar to us and we could study them to figure out how to increase our own longevity.
Yes, that’s a good way to find ways for longevity. The problem suffers that, by definition, the estimate of the age of outliers with models calibrated on non outliers suffers from the same point from Taleb’s paper from yesterday: the average & the tail are different beasts.
Can you think of any other logical ways (as opposed to Rory Sutherland's suggestion haha) to seek out longevity?
To solve the problem of the outliers above, let’s study the top 10% oldest, not the top 0.001%. More in general, easier to increase longevity by clipping the left tail of the age distribution than by increasing the right tail, IMHO.
Feels like that could be a tweet storm if you wanted to make it one.
