@ModernDad @CoachDanGo I have 8 Sleep, Apple Watch Ultra, Oura Ring 4, and now Fitbit Air. 8 Sleep overly optimistic. Oura/Apple Watch/Fitbit Air all very close. Love my 8 Sleep, but it's crap for real stats.

@CoachDanGo Got an 8 sleep? Would be cool to see how a smart mattress does too

For the next 7 days, I'm going to wear a Whoop, Oura Ring, Fitbit Air, and Apple Watch all at the same time. The goal is to see the differences in sleep and recovery metrics as well as user experience. Anything else would you want to see from this test?

@lost_nomad__ Manhattan Beach would be the exception. So good that Hawaii shipped it's sand in the 20's to form Waikiki Beach.

Sad to say, but unless you surf, California beaches are basically worthless compared to Florida or the Carolinas Odd because they are so glamorized. My only attempt at an explanation is that CA is just where Hollywood is so they promoted their own beaches over elsewhere

@ahazelrigg @bryan_johnson Is there any proposed mechanism to this? Is it an infrared sauna? As in might it be the infrared that is reversing the ALS? Humans are like plants and we need infrared and all the other rays from the spectrum of the sun or we wither.

@bryan_johnson Forgot to mention—3 hours!! 😳

@bryan_johnson Florida Dr. using same theory to reverse ALS. The results have been amazing—I would call BS if I didn’t personally know two of the patients. Their treatments are in a chamber (head out)—heat basically as hot as your body can handle without killing you.

@hubermanlab Have you ever had Caldwell on the show? I followed his book "Prevent and Reverse Heart Disease" and cut my LDL from 136 to 74.

93 years & 231 days old Ann Esselstyn dead hangs for 2 min 52 seconds! To set new WR. (Maybe we call it live hangs instead now?) Distal strength reflects many things.

@MobofJoggers @LandonoftheWest And let’s not forgot the Cybertruck is 1% of sales because it’s ugly as hell. Full size SUV that looks more like an R1S, Tahoe, Defender, etc. would crush it.

Anyone arguing that Tesla shouldn't build a large SUV because of low demand needs to explain why the heck Tesla built the Cybertruck that is only 1% of sales! @LandonoftheWest

Grok calls BS: No, the claims in this post are **not accurate**—they significantly exaggerate, misinterpret, and cherry-pick data from a real study while promoting a fringe view on cholesterol that's contradicted by mainstream scientific consensus. ### The Swedish AMORIS Study The post refers to the 2023 AMORIS cohort study (published in *GeroScience*), which analyzed blood biomarkers from ~44,000 Swedes (part of a larger cohort of over 800,000) measured in 1985–1996, with follow-up up to 35 years. Only 1,224 reached age 100. - **Key finding on cholesterol**: Being in the **lowest quintile** (bottom 20%) of **total cholesterol** was associated with a lower likelihood of reaching 100. However, **high total cholesterol did not increase the odds** of longevity. - A correction to the paper clarified: "Having high cholesterol neither increases nor decreases the probability of living to 100 years of age." - The study measured **total cholesterol**, not LDL-C specifically. It found no data supporting "every centenarian had high total cholesterol" or "highest LDL-C = longest lifespans." - Other favorable markers for centenarians included high iron and low glucose, but profiles were measured decades earlier (ages 64–99), and differences were small. This is an **association** in older adults, not proof that high cholesterol *causes* longer life. In fact, high LDL cholesterol in midlife is a well-established risk factor for cardiovascular disease (CVD), the leading cause of death. ### Claims About High LDL and Longevity - No evidence from this or other studies shows "the higher your LDL, the longer you live." Some observational data in very old age show an inverse association (higher cholesterol linked to lower mortality risk), possibly due to reverse causation (illness lowers cholesterol) or survivor bias. - Doctors like Uffe Ravnskov and Malcolm Kendrick promote cholesterol skepticism, but their views are not supported by major health organizations (e.g., AHA, WHO). Ben Bikman focuses on metabolic health but often downplays LDL risks in low-carb contexts. ### Dangers of Low Cholesterol - Some associations exist (e.g., very low cholesterol linked to higher risks of certain cancers, dementia, or hemorrhagic stroke in observational studies), but these are often confounded by frailty, malnutrition, or underlying disease. - No strong causal evidence that low cholesterol (<180 or <150 mg/dL) "skyrockets" cancer/dementia rates or that LDL <70 mg/dL triples brain-bleeding stroke risk. - Aggressive LDL lowering (e.g., via statins/PCSK9 inhibitors) does **not** increase dementia or hemorrhagic stroke risk overall, per large meta-analyses and AHA reviews. Benefits for CVD prevention outweigh rare risks. ### Statins and Life Extension - Statins robustly reduce CVD events and mortality in high-risk people (secondary prevention) and many primary prevention cases. - In primary prevention trials, all-cause mortality benefit is smaller (often days to weeks over trial duration due to short follow-up), but real-world data show significant reductions (e.g., 20–30% lower all-cause mortality in matched cohorts). - Statins do **not** just "damage mitochondria & hormones"—side effects (e.g., muscle pain) occur in some, but benefits dominate for those at risk. ### Why the Body Needs Cholesterol This part is mostly correct: Cholesterol is essential for: - Cell membrane structure and fluidity. - Precursor for steroid hormones (e.g., testosterone, cortisol), vitamin D, and bile acids (for fat/vitamin absorption). - Roles in immunity, brain function, and more. But the body makes all it needs (~80% from liver synthesis); dietary cholesterol has minimal impact on blood levels for most people.

.@bryan_johnson should I stop my statin?!?!

@SnazzyLabs Agreed, something like this please.

I wish Tesla would finally make a full-size SUV that was good. They would absolutely kill it if they did. The Model X is neither full-size nor any good.

@abc7chriscristi Disagree. Picked my Mom up last night and it was a breeze. Just got dropped off at 8:10 PM. Worse than yesterday, but not that bad.

Been flying over LAX Thanksgiving traffic for 11 years… this is the worst I have ever seen. This picture does not do it justice… ARRIVE EARLY!!! ✈️

@louieruvolo 1. Ask yourself what you can add/bring to the event rather than what you can get out of it. Always look for ways to be of service.
