The book emphasizes the critical importance of prioritizing mental health, brain health, cognition, and overall wellbeing in the same manner as physical health. It explores various lifestyle factors that contribute to enhancing these aspects of life, highlighting the benefits of incorporating them into daily routines. While, initially, adopting these habits may require effort, they eventually become easier to maintain and yield significant benefits for mental and physical health. Choosing enjoyable activities is key to sustaining these habits over time. Research underscores the substantial impact of a healthy lifestyle on reducing the risk of depression and promoting mental wellbeing, even among individuals with a genetic predisposition. Mental health and wellbeing are fundamental to daily functioning, cognitive abilities, and quality of life, influencing relationships, productivity, and personal growth. Similarly, cognition and brain health are crucial on both individual and societal levels, impacting daily functioning, economic productivity, and benefiting society. Promoting these aspects throughout life, from childhood to old age, fosters resilience, creativity, and societal flourishing. Ultimately, prioritizing brain health, cognition, and mental health enhances overall quality of life and contributes to a thriving society.
