Over the last few years there have been huge breakthroughs in research on our most precious possession, the brain. Work on neuroplasticity has led us to now understand that thoughts, emotions, behaviours and environment can change the structure and function of our brains. The implications for the impact of lifestyle, leisure, states of attention, media and life experiences on performance, memory, learning and brain aging are enormous. Furthermore, the way we use our brain impacts on our mental and physical health. It's never too late to invest time and effort into improving our brain.
