Something depressing is happen to humanity, and possibly even you. Our brains are degenerating and – in parallel – we’re seeing a worrying increase in mental illness across the world.

According to the World Health Organisation, our declining brain health is the greatest threat we face – more than cancer, diabetes or obesity. Individually and collectively, though, we can optimise our brain health and cognitive function – to improve mood, memory, stress resilience, sleep and ability to focus. How?
