Finnish sauna studies show a striking association with lower mortality. But after separating what the models actually adjusted for, the causal story becomes much less simple.

Research and evidence on aging, lifespan, healthspan, and interventions proposed to influence longevity.
Hormesis has one of the most attractive ideas in health science: a small stress can make a…
Fresh food can differ from stored food in oxidation state, flavor and nutrient content, but ORP is not a direct measure of healthfulness, antioxidant benefit or ‘life energy’. This article separates measurable redox chemistry from spiritual interpretation.
Tea does not have one normal ORP value. Redox potential depends on tea type, water, pH, temperature, oxygen, electrode setup and brewing conditions, so published mV values are not universal.
Elite athletes generally have lower mortality than the public, especially in endurance and mixed sports. But contact sports reveal a more complicated risk pattern.
I’ve already written about how I conducted studies of biological age of ten longevity enthusiasts using the…
Glucose is essential biology, not a toxin. It is a major fuel, especially for the brain and…
Yeast and worm studies reveal links between reproductive signaling, stress responses and lifespan, but they do not show that reducing human fertility extends life.
Andrew Weil’s diet overlaps strongly with Mediterranean eating, but some anti-aging claims go further than the evidence. Here is what holds up, what is uncertain, and why looking younger is not biological age.
Some human trials found lower testosterone with metformin, but the evidence is limited and contradictory. Here is what the studies actually measured.
Can a longer mental time horizon improve health or longevity? The evidence supports links with self-regulation, purpose and behavior, not cellular reprogramming.
Peter Attia is an interesting longevity figure for a reason that has little to do with any…
Liz Parrish’s gene-therapy self-experiment is scientifically interesting but uncontrolled. This article preserves the original longevity hypothesis while separating reported outcomes from independently validated evidence.
NMN reliably raises NAD-related metabolites in human trials, but evidence that it slows human aging or extends lifespan is not established. This guide separates promising mechanisms from demonstrated clinical outcomes and summarizes current safety data.
Does resveratrol slow aging or explain the French paradox? Human trials show some modest metabolic effects, but no evidence that resveratrol extends human lifespan.
Inspired by my earlier exploratory facial-age experiment, I analyzed images of David Sinclair from different years. The…
TallyAge uses a peer-reviewed cheek-cell epigenetic clock, but does a younger score mean slower aging or longer life? Here is what CheekAge validation studies actually show.
A critical review of David Sinclair’s reported longevity routine, separating personal practices from human evidence on NMN, resveratrol, metformin, aspirin and lifestyle.
I compared apparent facial age estimates from video screenshots. The results are interesting, but they do not measure biological age or prove rejuvenation.
Can food reduce chronic inflammation and help healthy aging? Evidence favors Mediterranean-style dietary patterns over lists of individual “anti-inflammatory” or “inflammatory” foods.
