The Science of a Healthy Brain: Habits, Longevity & Genetics
Brain ageing is not just a clock ticking down. It is a story written by your genes, your environment, and the habits you repeat for decades. Then there are the outliers. People who stay mentally sharp far longer than biology seems to allow.
In this Growth Lab Live session, Eloy Santos takes us on a journey into the hidden layers of brain ageing, using an in depth case study of the world’s oldest person as a recurring thread. What can extreme longevity reveal about resilience. What signals show up in the body long before cognitive decline. What parts of ageing look “modifiable” rather than inevitable.
We will unpack how genetics and lifelong lifestyle interact through mechanisms like epigenetics, the microbiome, and other molecular layers that quietly influence inflammation, repair, and brain function. Then we zoom out to the future. What therapeutic strategies are emerging right now, including new classes of drugs being explored to improve brain ageing, and what they can realistically deliver.

The core biological drivers of brain ageing, explained clearly
Why some brains resist decline longer than others
The roles of epigenetics and the microbiome in brain health
Where the science is heading next, from biomarkers to new interventions
Practical ways to think about “brain resilience” across a lifetime
