Blueberries measurably improve artery function and may slow cognitive aging by roughly 1.5 to 2.5 years, with benefits appearing most reliably at about one cup a day. Effects look strongest for vascular health, more mixed for blood sugar, and vulnerable to a surprising kitchen variable: blending with ripe banana.
Neuroscientist Richard Davidson says wellbeing is a trainable skill, not a fixed trait. He organizes this into four pillars (awareness, connection, insight, purpose) and shows five minutes of daily meditation for 28 days lowers IL-6, an inflammation marker, and shifts gut microbiome pathways; purpose best predicts longevity after age 70.
Immunologist Derya Unutmaz says AI could help medicine reach longevity escape velocity within 8 to 10 years (09:13), the point where treatments add more than a year of life per year. He describes reasoning models that outperform average doctors at diagnosis (49:20), predict disease years early (79:14), and could build personalized digital twins for testing treatments before humans take them.
