Seems pretty obvious to me. People who survive such conditions are probably stronger and more resistant on average.
Israel is currently ~50% Sephardic Jews, descendants from Middle Eastern/North African peoples. Holocaust survivors are almost all Ashkenazi Jews (European ancestors). If the study was comparing Ashkenazi Jews in the test group vs a control group that was majority Sephardic, it's possible the differences in lifetime was due to some cultural or genetic differences between the two groups.
The study doesn't seem to account for this confounding variable.

It's possible, but it also seems likely to me that such an event would totally devastate a person, and that we don't hear much from devastated people.
Earlier quoted context omitted.
The question is if it’s just a simple selection bias or did the stress of living under those conditions have had biological effects that are advantageous to longer life span. We know that cellular stress response and stress proteins have a positive effect on some functions that could induce longer life span, these tend to be most often related to heat and cold shock which is likely one of the key reasons behind why m…
Caloric restriction (extreme dieting) is well known to increase lifespan. Intermittent fasting shows tentative promise.
The survivor bias makes sense, those that would have died at 65-75 years maybe died then when tested by the hardships.
There was a recent story about how the inmates in the camps received the best healthcare available in German society at the time. That would certainly explain why so many years later we still hear about "new" survivors.

I’d love a link to this “recent story” which sounds distressingly like a very old and discredited claim of Holocaust deniers.
Kind of obvious but can it be simply a selection bias? The weakest died in the camps, the survivors would be the healthier, stronger, and therefore have a longer life expectancy than average.
