If you wish to observe the tempo at which you’re getting old, HRV, organic age take a look at, sleep, and VO₂ max are OK, however there are 12 deeper metrics value quantifying over time. And your wearable isn’t monitoring them but.
Scientists have mapped out 12 core processes that drive getting old, referred to as the 12 Hallmarks of Getting older. These could decide how lengthy and the way properly you reside. First outlined in 2013 then refined in 2022 as science developed, they type the muse of longevity medication right now. These assist information how researchers and clinicians measure, take a look at, and goal the biology of getting old.
After I traveled to the Amazon rainforest for a week-long longevity retreat, I anticipated to discover the standard pillars of wholesome getting old: motion, diet, restoration. What I didn’t anticipate was how deep we’d go into the mobile mechanisms behind them. The workshops went manner past life-style recommendation.
Throughout one-on-one consultations with the founders of Limitless Life, Dave Asprey, Dr. Tim Prepare dinner, and Marc Kielburger, every member obtained a personalised chart of the standing of their 12 Hallmarks of Getting older, displaying which mechanisms had been actively accelerating their organic age. Seeing your getting old, quantified in color-coded knowledge, is each humbling and empowering. It turns longevity from a imprecise journey into one thing seen, actionable, and deeply private.
Right here’s an instance of how over 600 biomarkers in addition to well being and life-style indicators assist Dr. Prepare dinner’s group assess every affected person’s getting old profile.

The 12 Hallmarks of Getting older
Earlier than dissecting the 5 classes I discovered within the jungle, right here’s a breakdown of what the 12 Hallmarks of Getting older are. It may get much more scientific than this, however it’s value having a high-level understanding of what we’re taking a look at. It’s additionally particularly vital to grasp that life-style decisions are the primary drivers impacting these hallmarks.
1. Genomic instability
DNA injury builds up over time from stressors, toxins, poor sleep, and even regular cell exercise. When your physique’s restore techniques can’t sustain, small errors begin slipping by way of, altering how your genes operate and slowly weakening your physique’s authentic blueprint.
2. Telomere attrition
Telomeres are the protecting caps on the finish of your chromosomes that get shorter every time your cells divide. Once they grow to be critically brief, cells cease dividing or die, slowing tissue restore and contributing to getting old.
3. Epigenetic alterations
Your genes don’t change, however the best way they’re expressed does. Getting older flips sure genetic switches off and others on, reshaping many issues from power metabolism to irritation.
4. Lack of proteostasis
Cells depend on completely folded proteins to remain practical. As that system begins to have cracks, misfolded proteins accumulate and mobile restore slows. It’s like making an attempt to construct a home by which the blueprints are scrambled, and the door finally ends up on the ceiling. In different phrases, the construction stops working the best way it ought to.
5. Deregulated nutrient sensing
It’s the scientific manner of claiming your physique will get worse at recognizing what you devour. Over time, these blended alerts could throw off metabolism, restoration, and power stability.
6. Mitochondrial dysfunction
As your mitochondria, your power engines, grow to be much less environment friendly over time, your cells could accumulate extra oxidative stress leaving them extra susceptible to break. The downstream impact of that will manifest in signs like mind fog, fatigue, sluggish restoration, and extra.
7. Mobile senescence
Senescent cells are the so-called “zombie cells” that linger when a cell stops functioning correctly however refuses to die, or go into apoptosis. As a substitute, they launch inflammatory alerts that injury close by wholesome tissue, improve reactive oxygen species, and contribute to getting old.
8. Stem cell exhaustion
As we undergo life, and particularly in athletics or bodybuilding, our stem cells are continually referred to as upon to restore microtears, joint stress, and tissue injury. Over time, each the quantity and effectiveness of those stem cells decline, lowering the physique’s capacity to regenerate. Scientifically talking, stem cell “exhaustion” doesn’t imply they vanish, it means their regenerative potential weakens over time as DNA injury, irritation, and stress within the surrounding mobile surroundings impair their capacity to resume and restore.
9. Altered intercellular communication
As signaling between cells turns into distorted, it might result in elevated irritation and immune dysfunction. It’s like static within the system, your physique stops speaking clearly with itself.
10. Persistent irritation
Low-grade, persistent irritation quietly drives most age-related ailments. It’s the gradual burn beneath many types of decline, and sometimes will get the nickname “inflammaging”.
11. Disabled macroautophagy
Autophagy is your physique’s self-cleaning system. When it declines, broken parts pile up inside cells, clogging renewal and restoration. Inner medication specialist, and pioneer of integrative longevity medication Dr. Prepare dinner advised me that whereas there’s no industrial testing accessible to quantify this hallmark, “if somebody isn’t fasting no less than 16 hours (periodically) and if their bio-age and inflammatory markers are elevated, then we assume this hallmark is lively,” he defined.
12. Dysbiosis
Our physique thrives in a symbiotic relationship with the trillions of micro organism that reside in our intestine. Nevertheless, when dangerous strains start to outweigh the useful ones, irritation rises, metabolism takes a success, and practically each system begins to really feel the impact. The intestine microbiome progressively shifts out of stability as we age as a consequence of a myriad of causes (antibiotics, nutrient-deficiencies, a weight-reduction plan excessive in ultra-processed meals, stress, and extra), and that microbial chaos spans from nutrient absorption to immunity and even temper.

5 classes I discovered within the Amazon
Understanding the 12 Hallmarks provides you the “what” of getting old. The Limitless Life program teaches you the “how”. Over a number of days of workshops deep within the rainforest, we explored some highly effective levers that will affect these hallmarks. What’s attention-grabbing is that since nothing within the physique works in isolation, neither do these 12 hallmarks. They’re interconnected, so whenever you enhance one, you create ripple results throughout the others.
Listed here are 5 classes that stood out all through the week.
1. Diet
Each meal you eat sends messages that affect how your cells reply, how effectively your mitochondria produce power, and the way your physique manages irritation. It’s one of the crucial direct methods you may affect a number of hallmarks of getting old. Cease leaping on the subsequent weight-reduction plan development, and take the time to pay attention and observe how your physique responds to what and whenever you eat, and be keen to adapt because it modifications. Completely different phases of life, hormones, and coaching masses demand completely different macros and micronutrients. Asprey famous throughout one of many workshops to “not method meals with concern, method it with consciousness,” as a result of “your nutrient standing helps you deal with your surroundings higher.”
Steady glucose displays can present how your physique reacts to sure meals in actual time, whereas genetic and methylation testing can reveal how properly you course of vitamins.
That consciousness means understanding what you’re consuming at a deeper degree, like being aware of oxalates in sure vegetation (sure, Asprey nonetheless isn’t a fan of kale) or cooking mushrooms completely to keep away from compounds that may irritate arteries.
2. Personalised supplementation
Asprey shared that simply within the final decade, 50,000 new research had been printed on dietary supplements. So when you suppose you had been confused about what works and what doesn’t, it’s not even half of it. Dr. Prepare dinner added that analysis in longevity medication doubles each 4 months. Irrespective of the place you’re in your well being journey, dietary supplements are crucial to maximise your healthspan and goal weak factors inside your particular person getting old profile, whether or not it’s DNA restore, mitochondrial assist, or nutrient sensing. A number of members had been requested to reshuffle their complement stack as they reviewed their take a look at outcomes.
3. Connection
This was essentially the most surprising takeaway. Kielburger shared a number of notes on how connection instantly impacts mobile well being and inflammatory markers. Research have proven that loneliness was related to increased ranges of C-reactive protein and modifications in gene expression in immune cells. So, whereas your wholesome journey may really feel like a path of isolation, it’s value placing within the effort to nurture shut relationships as a result of it might actually add years to your life.
4. Transfer constantly
The notion that muscle is a long life organ has been well-established. However it seems that even short-duration however constant exercise goes a great distance. For instance, REHIIT, which is a brief maximum-intensity dash exercise.
Train prompts autophagy, stem cell renewal, mitochondrial restore, and nutrient sensing, making it one of the crucial potent anti-aging instruments we’ve. All three founders highlighted that you would be able to’t complement your manner round motion.
5. Superior biomarker testing
Lastly, the thread that ties all of it collectively: knowledge. One of many workshops made it clear that the majority of us are taking a look at an incomplete well being dashboard. Typical lab exams, like ldl cholesterol or thyroid panels, provide a slender view of well being, and don’t inform the complete story. As Dr. Prepare dinner defined, true longevity medication requires digging deeper. His group ran coronary CT angiograms on all members to see what was truly taking place contained in the arteries, together with exams that reveal how infected these arteries could be, together with CRP, fasting insulin, HbA1c, homocysteine, ApoB, Lipoprotein(a), and oxidative stress.
Moreover, measuring key biomarkers like intracellular NAD ranges, DNA methylation, and microbiome stability reveals which hallmarks are thriving and which want consideration.
The Takeaway
Over the previous couple of years, I’ve studied the 12 Hallmarks of Getting older at a floor degree, sufficient to grasp the framework, however by no means fairly seeing the way it all comes collectively in observe. What I preferred essentially the most in regards to the Limitless Life program was watching these hallmarks shift from tutorial ideas into actionable interventions.
Plus, the group made it clear that regardless of what number of purple flags present up on a person’s evaluation, you’re not speculated to deal with them abruptly. As a substitute, they focus you on the lowest-hanging fruit, whether or not that’s optimizing your hormones, refining your diet, or adjusting your complement stack. This longitudinal method is what units it other than most of what I’ve seen within the longevity area. You’re getting a deep understanding of your distinctive getting old profile, adopted by a deliberate, phased technique that evolves as your physique modifications and as your take a look at outcomes shift over time.
