The Science of Longevity, a free health course on Tomo

The Science of Longevity

Like Duolingo, but for The Science of Longevity. Tomo turns the whole topic into a game you play five minutes a day, until it actually sticks.

For the part of you with thirty open tabs that never became anything.

A short one: 11 levels across 2 sections, about 22 minutes end to end, roughly 4 days at five minutes a day. It moves through Separating Proven Interventions from Hype and Biological Mechanisms and the Molecular Frontier. It starts from scratch.

Key ideas in The Science of Longevity

  • Cardiorespiratory fitness (measured by VO2 max) predicts survival odds better than classic risks like smoking, high blood pressure, or cholesterol
  • Moving from low aerobic fitness to above-average fitness yields one of the largest mortality risk drops in clinical medicine
  • Muscle tissue acts as a major glucose sink that prevents insulin resistance and metabolic dysfunction
  • Physical strength provides the stability needed to avoid disabling falls, which are major late-life mortality triggers
  • Simple strength markers like grip strength predict whether an older adult will survive an acute illness or hospital stay
  • The brain's self-cleaning glymphatic system activates almost exclusively during deep sleep to clear toxic metabolic debris
  • Chronic sleep disruption keeps systemic inflammatory pathways turned on, accelerating cellular aging and cardiovascular decline
  • Minimizing industrially processed foods loaded with added sugars and refined fats consistently lowers mortality across all cultures
  • Keeping resting insulin low by avoiding frequent blood sugar spikes protects cells from premature aging
  • The exact macronutrient split (fat versus carbohydrate percentages) matters far less for lifespan than food quality and metabolic control
  • Short-lived lab models like yeast, worms, and rodents have vastly simpler metabolisms and protective biology than long-lived humans
  • Many anti-aging compounds that rescue short-lived animals from early death show no meaningful life extension when tested in humans
  • Epigenetic clocks track statistical cellular patterns, not whether you actually avoid heart attacks, stroke, or death
  • Improving a proxy score or biomarker does not guarantee that a person will live longer or stay disease-free
  • Observational studies show correlations between habits and survival but cannot easily untangle the habit from the person's overall lifestyle
  • People who routinely adopt healthy habits (like drinking green tea) also tend to exercise more, smoke less, eat better, and have higher incomes
