Summary
In this episode, we break down the science behind cognitive reserve, brain aging, and why memory and processing speed may play a bigger role in long-term health than most people realize. You’ll hear how 95-year-old scientist Dr. Michael Crawford still produces complex research, what makes superagers different at the brain level, and which daily habits may help protect your cognition over time. We cover DHA and seafood intake, sleep and the glymphatic system, chronic stress and hippocampal damage, the difference between brain reserve and cognitive reserve, and the long-term findings from the ACTIVE trial. We also look at practical ways to train processing speed through walking in busy environments, racket sports, dancing, fast-paced games, and rapid visual scanning tasks. If you want to protect your memory, stay independent longer, and build a stronger brain for later life, this episode gives you a clear starting point.
