Workers in some occupations live years longer than those in others. French life tables and original Spanish mortality calculations show the differences, and what they do not prove about the effects of work.

Research and evidence on aging, lifespan, healthspan, and interventions proposed to influence longevity.
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.
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.
Which athletes live longest? A critical look at 165,000 elite athletes, a 44-sport ranking and the NFL paradox, with a comparison of the evidence and practical lessons for recreational sport.
This article revisits an informal experiment in which I compared photographs with online age-estimation tools. The central...
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.
Does metformin lower testosterone? A trial in 70 men suggests it can, but data from 886 other men complicate the story. What the human evidence actually means.
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 can raise blood NAD-related metabolites, but does it improve health or slow ageing? A critical review of 2026 evidence, 15-trial meta-analysis and new 24-week trial.
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.
An evidence audit of David Sinclair’s 2026 longevity routine: NMN, resveratrol, metformin, nattokinase, epigenetic reprogramming, clinical trials and what remains unproved.
I compared apparent facial age estimates from video screenshots. The results are interesting, but they do not measure biological age or prove rejuvenation.
