On this episode of Performance People, we welcome Dr Tommy Wood; neuroscientist, performance coach and, in his own words, “elite professional nerd.” An Associate Professor of Pediatrics and Neuroscience at the University of Washington, Tommy also co-hosts the Better Brain Fitness podcast and serves as Hintsa Performance’s head scientist in motorsport.

In this conversation, Tommy unpacks how we can “age-proof” our brains using his simple Three S Model: stimulus, supply and support. He explains how learning complex skills, social interaction and challenging our minds provide the right stimulus; why cardiovascular health and nutrition are essential to supply the brain with oxygen and fuel; and how support; through sleep, recovery and stress management is critical for adaptation.

Tommy shares practical ways to build brain fitness without adding pressure or guilt, suggesting that small, realistic changes like 10 extra minutes of sleep can make a real difference. He challenges the myth that cognitive decline is inevitable with age, highlighting research that shows physical activity and even brisk walking can improve memory and increase brain volume.

Engagement, movement and connection, Tommy argues, are the true keys to long-term brain health.
