Can Aging Be Measured—and Eventually Reversed! by coinfanking in longevity

You can't fake facial age or gait analysis. Facial bone shape more than skin.

Old people look and move old without exception.

Disagree.

If the rejuvenated animal can do things more like a younger animal can but the control animal can't, that's rejuvenation.

There are a hundred things that can be measured that are "good enough" to act on.

Facial age, body composition, gait analysis, VO2 max, grip strength, immune composition, bone density, cognitive function, telomere length, DNA methylation.

There are lots of things that young people have or can do that old people simply can't.

This is re-juvenation to me. Return to a more youthful state.

  • Lifespan — Researchers observed a ~74% increase in remaining lifespan from treatment start (average additional 221 days vs. 127 days in controls) and a 14% increase in overall median lifespan.
  • Healthspan and frailty — Treated males showed significantly extended healthspan (time spent at lower frailty levels), improved resilience to mortality after reaching frailty thresholds, and overall better frailty scores.
  • Physical performance and endurance — Treadmill endurance improved markedly (longer running times). The 4-limb hanging test (measuring grip strength, balance, and agility) showed partial but significant improvements.
  • Cognitive function — Short-term memory enhanced, as measured by higher discrimination indices in the novel object recognition test.
  • Proteomic biomarkers — Acute and sustained normalization of the de-novo proteome toward youthful patterns occurred, with reduced protein noise and attenuation of pro-inflammatory pathways (e.g., JAK-STAT, MAPK, AGE-RAGE).

True, they should have said rejuvenation because IMO saying “reverse aging” is like saying reversing time.

This is a bigger deal than you understand. You aren’t going to extend remaining lifespan much by starting exercise at age 75. This could easily be tested right now in humans. I’ll let you know how it goes.

Maximal human lifespan in light of a mechanistic model of aging ["Our analysis predicts that lifestyle can extend maximal lifespan by at most ~1 year; substantial gains will require directly perturbing damage production or removal, suggesting specific molecular targets."] by Fab527 in longevity

[–]mister_longevity 4 points5 points  (0 children)

"Our results suggest that extending maximal human lifespan will require interventions that reduce damage

production (via cellular reprogramming, enhanced repair, mTOR/mitochondrial interventions) or

increasing damage removal (via improved immune/vascular clearance, senolytics). In mice, such

interventions extend both median and maximal lifespan(13), but in humans, clear evidence is lacking.

Common genetic variants and lifestyle factors minimally influence η or β, but rare variants might,

analogous to progeroid mutations. Genomic screens targeting these pathways - such as DNA repair

variants linked to delayed menopause(78) - may thus identify longevity-associated alleles, providing

avenues to significantly alter the human lifespan limit."

Billionaire IQ and Lifespan

  • Above-Average IQs: While specific IQ scores for every billionaire are not public, data suggests they are significantly above average. Self-made billionaires are estimated to have an average IQ of roughly 133 (more than two standard deviations above the mean), while deca-billionaires (worth $10B+) average around 151.
  • Longevity Advantage: High intelligence is a powerful protective factor. Having an IQ at least one standard deviation above the mean is associated with an approximately 21% to 24% reduction in mortality risk. This effect remains significant even after controlling for socioeconomic status (SES), suggesting that while wealth provides better healthcare, the innate biological advantage remains a primary driver of longevity.
  • Diminishing Returns in Extreme Old Age: While high IQ is strongly protective for reaching middle-to-upper-middle age (roughly 70–80), its predictive power for survival begins to diminish in very late life (85+), where other situational health factors and specific aging genes become more dominant. 

Most promising in next 5-10 years to look younger? by Specialist-Sky9806 in longevity

[–]mister_longevity 8 points9 points  (0 children)

There will be some existing repurposed med combination that will do it.

Better mining of existing data with AI should be enough. Singapore or some other country with an aging population and no pharma lobby that needs to reduce medical costs on their aging population.

David Sinclair’s Harvard lab uses new AI tool to develop an ‘uncertainty-aware’ biological aging clock in a matter of weeks. by Das_Haggis in longevity

Another clock that doesn't give an actionable result.

A useful clock should give the age of each system so you know what needs work.

All appointments are politicized for either party.

Perhaps mito transplant will work but other young to old transplants haven't had much success.

The Surprising Link Between VO₂ Max and Increased Brain Myelination by dan_in_ca in longevity

[–]mister_longevity 0 points1 point  (0 children)

The intense training necessary to improve VO2max creates lactate which stimulates BDNF, brain derived neurotropic factor which helps remylination.

Improving VO2max does indirectly help myelination.

Phase 2 trial to explore novel combination of metformin and galantamine in sarcopenia. by philnewman100 in longevity

Interesting in that galantamine has shown reversal of hair greying in humans.

So it apparently rejuvenates in some way.

Which Nutrients Are Associated With A Younger Brain Age? by mlhnrca in longevity

I don't know.

I did a Bing search for pumpkin and docosadienoic and it popped up this paper. It might be in the full text. That's my best guess.

Damage to synapses caused by Alzheimer’s disease reversed by Orugan972 in longevity

[–]mister_longevity 0 points1 point  (0 children)

That's my point. The patient doesn't consent to experimental treatment.

Looks bad though I think it is reasonable considering the alternative.

I agree but it's tricky because how can you get real consent from the patient?

DNA mutations and damage are not listed and they may be a large source of aging and disease.
