This is about those aged over 100, not 110 which is a completely different ballpark... Besides that, all my relatives lived close to 100 and they certainly hadn't a healthy lifestyle nor are they japanese nor had they access to the current medical breakthroughs. I assume the secret is mostly genetics and it is easy for me to see how 100k are aged over 100 in Japan.

  Lifespan genetics research is all over the place, partly because it is hard to get adequate statistics. There's currently a new preprint paper by Shenhar et al. that suggests life expectancy is actually heavily influenced by genetics if you account for the confounding factors correctly.

  Many diseases that shorten lives have increased chances due to genetics from Alzheimer’s to diabetes or some heart diseases(the leading cause of death) . While longer lives may not be directly inheritable, shorter lives absolutely can be, good genetics does play a role to living long .

> I assume the secret is mostly genetics That, but also various factors during one's life - most importantly, ample and healthy food (especially during fetal growth, childhood and youth), a lack of exposure to known damaging factors for physical and mental health (smog, noise, tobacco, alcohol and other drugs), and a lack of wars and other forms of violence. The top killers in the Western world are cardiovascular diseases (strongly linked to food) and cancers (strongly linked, again, to food but also to drugs). A safe working culture (both in business and in private) is also a good thing to have - the typical lackluster attitude towards workplace safety is a top cause of workplace accidents both fatal and non-fatal but serious.

  1 in 3 Japanese smoke. That's down from 2 in 3 about 30 years ago. I can tell you very easily why Japanese live longer than Americans, since I have spent abundant time in Japan.

    I suspect two things, low-calorie diets consisting predominantly of fresh foods and vegetables. And active lifestyle. It is unreal how much a good diet and walking everyday will change your entire life.

      I recently had an experience where I needed to do physical labor about 16 hours a day for two weeks, at the same time there was hardly any time to eat so I had to eat very small and simple meals. At the end of the two weeks I felt amazing.

        I think this works well for relatively short bursts, but if you made it a regular habit your body would start to break down after a year or two.

  Can't speak for the one you're replying to, but when it's just about the age of 100 it's not particularly difficult to verify. Take my great-grandfather, for example, who died at nearly 100. I have photos with him and my father, when the latter was a child, and I've seen photos of my father from his whole lifespan of course. I have photos of my great-grandfather from way way back in time, with references (including newspaper articles with photos). And so on and so forth. There's no way his birth certificate and church records could have been faked. And that actually goes for my great-great-grandfather too. On my mother's side, I was a little boy when I met my great-great grandmother who was already 90, and witnessed her living to, guess what, nearing that other age mentioned. And, again, there are records and photos going way back to when she was born. At an old people's home nearby I got to know a gentleman for some years, he died this year at 99. Again there are records in numerous places documenting his age and where and when he was born (and he grew up nearby my grandfather's place). And at that same old people's home there's a vital lady who's 105, and, again, unless you believe all public documents and church records are fake, she's as real as it gets. She has a daughter who visits, she's in her seventies. That daughter has children of her own, and her children also have children. It's when you get to all the 115-120 year olds in remote regions you start to see the fakes. And it's not difficult to spot when you look, the statistics are all skewed - unlike in places like most of Japan, just to get back to the original story.

    But nobody is doubting that these people exist, or saying that their documents were faked maliciously. Back in my grandparents' time, they had a child, then a few years later they went to register the child, the clerk asked "how old is she?" and they said "7 or 8" when she was 11, for example. My grandmother never knew her birthday, or her birth year. We just estimated, even though she was very much real.

My maternal grandparents are currently 98 and 96 and the last time I visited them grandpa said that his father didn't live to age 60. Meanwhile he has an older sister who, while bedridden, is very much alive at 100. I suppose the necessary medical breakthroughs happened in the second half of the 20th century, as no one, including the people in question, anticipated they would live this long. Grandma even stated in her will that my second oldest cousin would inherit the apartment - supposedly to have "a better start in life when she grows up". That was 30 years ago and my cousin's oldest child should be in high school now right now.

> This is about those aged over 100, not 110 which is a completely different ballpark Is this some kind of new math? 100 and 110 are within 10% of each other, which seems very much in the same ballpark to me.

  Your chance of dying is roughly 50% per year in that range. 2^10 = three orders of magnitude difference in survival

  The chance of dying is not linear with age.

  They are not within 10% of each other when you consider human mortality rates. Ie if you live to 100, you do not have 10% chance of living to 110. Eg this study says: "Three percent of females and 1% of males in the 2019 birth cohort, given age-specific mortality rates in that year, are projected to survive to 100 years old. Only 0.4% of females and 0.09% of males will survive to 105 years which is 10 times rarer than survival to 100. Survival to 110 years is 150 times rarer for females and 333 times rarer for males (0.02% for females, 0.003% for males) than living to 100.
