Can Your Brain Grow Again at 65? Neuroscientist Tommy Wood Thinks So
Neuroscientist Tommy Wood argues the aging brain stays adaptable later in life — and shares his '3 S' method (Stress, Strength, Stimulus) to keep it sharp.

For decades, scientists believed that the aging brain could only decline. But according to neuroscientist Tommy Wood, our brains may remain surprisingly adaptable — even later in life.
His approach is based on the "3 S" method:
- Stress (the good kind): Challenge your brain with new and demanding activities such as learning a language, playing an instrument, or solving unfamiliar problems.
- Strength: Regular physical exercise, especially resistance training, supports brain health and may stimulate beneficial biological processes.
- Stimulus: Continuously expose yourself to novelty and lifelong learning instead of settling into repetitive routines.
The idea isn't that the brain literally becomes younger overnight, but that it can maintain or even improve its structure and function through consistent stimulation and healthy habits. Research on neuroplasticity increasingly supports the notion that our brains remain capable of adaptation throughout life.
Brain Geek Take
Your brain loves comfort less than you think. It thrives on challenge, movement, and curiosity. If you want to stay mentally sharp, don't just exercise your body — exercise your mind every single day.
