But it conforms to many of the others... it's only 20 miles inland from the pacific, and has an (albeit warmer than normal) Mediterranean climate... "winter" lows are rarely below the mid 40s.
I grew up in the Loma Linda area as a Seventh-day Adventist (though my family left Adventism when I was a teenager after reading some books that explained why some of its core teachings are unbiblical). My grandparents all lived past 90, and my great-grandfather died at 100.
Epidemiologically speaking, I think SDAs in general live longer because they don't smoke, don't drink, and don't eat meat -- and have a religious community in which doing so is against God's law. It also doesn't hurt that they keep Sabbath, which means everyone who doesn't work in healthcare or emergency services has a mandatory day off, no work allowed.
Smog in the whole Inland Empire area is still pretty bad, especially in the summer. It gets pretty hot in the summer, not very cold in the winter - a lot like LA, but hotter :)
Which makes sense, if you assume that any given cohort will have some percentage hit 100 years; and then the cohorts that somehow have people removed "early" will have lower percentages.
For example, the cohort that includes people sent to WWII will have many that died in that war, even if they would have hit 100 otherwise.
And a group that "outlaws" some of the major causes of premature death (alcohol, smoking) would then have more cross the line.
Interesting correlation: Eating more meat seems to cause people to grow larger, but there is no strong evidence that being physically larger has intrinsic benefits outside of physical strength (which is arguably not very important). You do however need to eat more, you're more likely to get cancer, heart disease, suffer from chronic inflammation, etc.
Interestingly, statistics about growing larger are often used to support more meat eating by meat advocates. There is a lot of talk about protein quality, and the implication is that smaller people are disadvantaged – as though they must be growing less by all measures, not just stature. It isn't so clear that this is true though, and there's plenty of evidence to suggest we shouldn't strive to grow larger (either in stature or in lean mass).
I'm not saying there is a certain truth in there at all. I do find the correlations fascinating though. It defies a lot of what I understood about nutrition for most of my life so it's definitely something I'd like to see more data on. I'm open to a meat-based diet being superior overall (or any tasty diet, really).
My health-obsessed doctor friend told me that muscle mass is a good predictor for health in later life, which was surprising to me (I thought fitness, heart/lung etc was the thing). I wouldn't dismiss it. :)
It makes me think of all those reports that claim that having a single glass of wine per day makes you healthier.
It's probably the case that people who have just one glass of wine are drinking socially, and therefore have friends, and having friends is an indicator of having status and health. The alcohol itself is poison but one glass is more than offset by otherwise living a good life.
Oh they studied this! It's because if you're the kind of person who can afford a glass of wine every day, you're also the kind of person who can afford health care. In USA at least.
Here's the best source I can find right now:
> The study authors write that “the observed cardiac benefits of alcohol have been hypothesized to be the product of residual confounding because of favorable lifestyle, socioeconomic, and behavioral factors that tend to coincide with modest alcohol intake.”
It's harder to keep muscles as you grow old. More muscles is indication of good metabolism, which correlates with good health (less chance of getting metabolic syndrome etc, somewhat relevant: https://betterbodychemistry.com/obesity/metabolic-syndrome-m...)
Muscle mass in that equation would be relative to stature, so being smaller wouldn’t be a disadvantage in that regard.
In my comment above I didn’t mean to suggest strength is useless or irrelevant so much as that scaling it up by a few percent doesn’t appear to confer meaningful benefits. Someone 5’6” is probably strong enough to do everything someone 6’ can do in every day life, even without modern technology. You can generally scale down what you need to, and for exceptional things, you can likely recruit and partner to solve the problem or apply intelligent solutions.
I’m open to being wrong. Like I was saying, this is just based on correlations I’ve been reading about lately and far from peer reviewed study results.
Of course. I’m speaking from a biological rather than cultural perspective (as much as you can separate the two, at least). I’m more so interested in what supports longevity as opposed to what supports dating prospects.
I suppose my question is, all other things being equal, would we be healthier if we were of smaller stature? Some data indicate this might be the case, and that’s interesting to me. I suppose my upbringing and culture encourage a “bigger is better” mentality.
A lot of data indicate this could simply be a case of people growing larger because they have access to more food. Genes express, people grow, but the main issue isn’t stature so much as having so much food readily available after they finish growing. Perhaps we eat too much and stature has little to do with it; it’s just a byproduct of access to calorie and protein rich food.
How is physical strength unimportant? Stronger people are harder to kill (h/t Rippetoe) and improved strength also helps to avoid carpal tunnel syndrome and neck/back pain for those of us at a computer all day.
I can't think of much a human can accomplish with exceptional strength that will aid them in normal day to day life (generally speaking). There are exceptions, but those exceptions would apply only to rare circumstances. Sort of like, say you're going to be murdered by some totally jacked guy, hypothetically, and all you have to defend yourself is your bare hands. Okay great, it would be nice to be ridiculously strong. But how often does that happen to you? Or anyone?
Most predators will kill us even if we're ridiculously ripped, so that's not important either. In most cases, intelligence seems a lot more useful for avoiding or navigating these situations.
There's also a lot to be said for having moderate strength in a wide range of motion. That can matter a lot in a much broader variety of situations where physical strength matters, and it's far more realistic to attain and sustain.
Avoiding carpal tunnel doesn't require special levels of strength so much as normal fitness. It requires regular movement and preventing weaknesses. I'm not saying we should all vegetate at a computer, I'm saying that the evidence seems good that being 5% larger/stronger (or whatever the figure was) is not particularly helpful, and instead potentially harmful.
For example, regular yoga will probably resolve most (not all) people's mobility and repetitive stress issues. They will not need to be large or strong for this to work.
Although it would help if they were stronger, this isn't the result of them needing to begin a Starting Strength program. My original point was more so that stature and muscle mass might not benefit you beyond a certain point – I don't doubt at all that being fit is still tremendously beneficial.
It's also pure speculation. I read about this stuff for fun and I know just about nothing about anything. Maybe being larger really is a net positive and I just need to be pointed to the right data.
I'm not going to argue this with you. I'm not up for being dragged into a stupid internet fight with a random internet stranger. But this might interest you:
Right, and I think an important distinction here is sheer strength from general physical fitness.
If someone is relatively weak with below average lean mass, lower than average markers of muscular strength, etc. it seems like the consensus is that they are statistically likely to die or get diseases earlier in life. On the other hand, being on the other side of that seems to yield diminishing returns. It’s great to be fit, but being abnormally strong on the other hand doesn’t appear to increase your lifespan proportionally to your strength.
It helps avoid frailty and it allows you to continue exercising well into old age, for two things. It delays the downward spiral of poor fitness and weak bones that eventually does most of us in.
That’s also an interesting anticorrelation with how we normally relate metabolism and body size; smalller organisms tend to have faster metabolisms and live shorter lives versus much larger organisms.
Maybe the key is being smaller but also having slower (or rather, “calmer”) metabolic rates.
I believe what you want to be is a small member of a large species. Large dogs live much shorter lives than small dogs. Women tend to live longer than men (height or mass probably isn't the only factor here, but this fits the general pattern so one imagines it helps). Giants -- people well over six feet -- tend to live shorter lives than people of ordinary stature. My grandmother was about five feet with a straight spine. With a curved spine in her early hundreds she was probably less than 4'6", but she was still there. She had about two giant lifetimes. If you stacked her on top of herself you would have one giant (until her ever more flexible spine folded in two).
> but there is no strong evidence that being physically larger has intrinsic benefits outside of physical strength (which is arguably not very important).
Actually remember reading that a number of studies have linked short stature with heart disease. I’m not up-to-date on the latest research on this. But whether shorter or taller you do the best you can with the factors within your control - nutrition, exercise, sleep, etc. Anecdotally two friends’ fathers in elementary school died way prematurely, both quite short of stature.
In the people that use meat’s superior satiety to stay lean, you see lower inflammation, IGF-1, insulin … etc. On a purely meat diet with loads of protein, my IGF-1 was 90, a z-score of -1.
That's an interesting point. I'm not sure how much genetic overlap we have with whales, but I suspect it's significant. I wonder what allows them to live so long without getting cancer, for example. I can see why they wouldn't get cardiovascular diseases (in humans this seems to be mostly induced by diet and sedentary lifestyle), but it seems likely that there's more to it.
No it isn't? Elephants develop cancerous cells at the same rate per cell as every other animal, but have better biological methods of destroying them when those cells do turn cancerous.
If I may posit an idea. It's not that poor record keeping leads to blue zones.
It's that not caring about the trivialities of paper pushing and imaginary rules that current Western governments use to exert their power, helps one live longer.
Now why do guys like you and me know what a land registry is? Is this essential to our survival, in the hunter-gatherer sense of the word? No. What are we then?
Loma Linda's core contributing factors seem to be:
* High incidence of vegetarianism
* High incidence of non-smokers and non-drinkers
* Strong religious / social community
* Access to great healthcare
All while having birth records that are just about as accurate as anyplace else in the United States.
