    Sexual activity and stress levels (HPA activity) may determine longevity

    The study below tried to tease out the main factors affecting the longevity of the legendary naked mole rat - the animal with longest lifespan in its genus, and the sole mammal known to be virtually immune to developing cancer. Most of the biological/biochemical findings in regards to naked mole...

    David Sinclair On Extending Lifespan

    David Sinclair talking about how to extend lifespan. I've seen him making the rounds on the interview circuit (Joe Rogan, Google Talks, etc.) over the past year or so. It looks like he's been getting quite a bit of attention. 9:19 - "Well the clock of aging is due to the loss of information...

    Blue Light Accelerates Aging And Reduces Lifespan By More Than 50%

    In one of his interviews, Peat mentioned that red light exposure may be the most fundamental protective factor in nature, and that a deficiency of it (as commonly seen in Western lifestyles) may be the main driver of systemic aging and the diseases associated with it. The study below provides...

    A High-carb Diet May Explain Why Okinawans Live So Long

    Most people have heard of the so-called Okinawan "miracle" - i.e. the high ratio of centenarians per capita on that Japanese island. While that ratio is artificially elevated due to increased emigration after WWII, there is solid evidence that Okinawans have better systemic health than the rest...

    Low-protein High-carb Diet Has The Same Benefits As Caloric Restriction

    A recent study posted on the forum claimed that low carb is better for weight loss than other diets. Low Carb More Effective In Weight Loss Than High Carb? But the key question which so far most dieting studies ignore is this. Is the diet actually improving health and increasing lifespan...

    Longevity Is NOT In Your Genes, It's In Your Choices Of Lifestyle And People

    Yet another big hit against the genetic explanation. Not only is longevity not due to genes but it can also be largely controlled by whom you associate with. Estimates of the Heritability of Human Longevity Are Substantially Inflated due to Assortative Mating The Key to a Long Life Has Little...

    There Is Probably No Limit To Human Lifespan

    The current ruling dogma in medicine is that human longevity is most likely genetically determined, and seems to be capped at about 125 years. The main arguments given in favor if this hypothesis are the apparently exponentially rising odds of dying with increasing age and the fact that no...

    Cheetahs In Captivity Die Early Due To High PUFA / Low Glycine Diet

    I know cheetahs are not the most applicable model to humans but the dramatic decrease in life expectancy for captive cheetahs caught my eye, as well as the fact that the two factor (high PUFA, low glycine) were the only metabolic abnormalities identified so far. I think the glycine deficiency is...

    More Intelligent People Live Longer

    Ray has written many times about the links between metabolism and intelligence, and metabolism and longevity. The mainstream view if that both traits (intelligence and longevity) are genetic and unrelated. Previous studies that found correlation between intelligence and lifespan ascribed it to...

    Life Expectancy Is Lower In Parts Of U.S. Than Iraq

    Life expectancy is lower in some parts of the U.S. than in Iraq, the Philippines and North Korea

    Vitamin B2 (riboflavin) Reduces Lipofuscin, May Extend Lifespan

    There are few reliable treatments of the so-called "age spots" officially known as lipofuscin. Ray has written about the role of iron, PUFA and estrogen in the formation of this skin pigment and has suggested that vitamin E may be one possible treatment. Now we can add vitamin B2 to the list of...

    Facial Deformity May Be An Indication Of Early Life Stress

    A few people have asked Peat about bodily facial and torso deformities and he has said it is likely due to high estrogen, especially in early childhood. This recent study seems to add evidence to that hypothesis by showing that crooked bite (a type of facial deformity) is an indication of stress...

    Lifespan / Longevity May Be Tied To Environmental Conditions

    While I do not agree with the main assertions of the author on "rate of living" theory, he does make a few very important points, including the vital importance of mitochondria and metabolism for evolution and lifespan. Also, he lists a few examples of species where lifespan doubled simply...

    Low Socioeconomic Status Affects Life Expectancy More Than Obesity

    I think the "war on obesity" we are seeing currently, while well-intentioned, may be a bit misplaced as obesity itself has now been tied to low socioeconomic status. This study has now found that that low status is more important for your overall life expectancy than how much you weigh. Given...

    Aging May Be An Epigenetic Process

    The study focused on turning adult cells into stem cells (which is something yet to be proven safe or replicable in humans), the important message is that aging seems to be an epigenetic process, and as such fully reversible. This matches well with the other studies I posted showing glycine...

    Regular Aspirin Intake Can Save The US Almost $700b In Healthcare Costs

    I am starting to see more and more "bold" news articles that seem to prepare for an official change in policy by the FDA. Given that nothing so far has been able to stop the rising healthcare costs or improve outcome for patients in the medical system, the powers that be are getting desperate...

    Vitamin D3 Extends Lifespan By Preventing Toxic Protein Buildup

    Over the last 6-9 months I noticed that often people who communicate with Peat over email get a recommendation to supplement with vitamin D. When asked why, Peat said that he knows quite a few people who recovered from "very serious symptoms" by using vitamin D. Well, this new study shows that...

    Mice And 25 Different Diets,which One Increases Lifespan The Most?

    I'm not sure if this was posted yet? The main question is if the carbs in the chow contained protein within the fruit and how much,did they allow for this? "In invertebrates, reproductive output and lifespan are profoundly impacted by dietary macronutrient balance, with these traits achieving...

    Inhibiting Serotonin During Protein Feeding Doubles Maximum Lifespan

    This study is actually on the effects of a high protein diet on brain neurotransmitters and lifespan. It was done in fruit flies but the serotonin in those fruit flies are essentially the same in humans. So, the results should hold. One of the big takeaways from the study is the explanation of...

    Calorie Restriction In Peat Thinking [Life Extension]

    I just read this: http://www.economist.com/news/briefing/21704788-fight-cheat-death-hotting-up-adding-ages It explores life extension through calorie restriction. Peating seems to involve a lot more calories than normal Explanation?
