You're not broken — your world is loud.

In an era of distraction, stress and mental fatigue The Focus Index offers a humane and scientifically validated way to recapture clarity, attention and peak mental performance.

Packed with practical advice, science, and the wisdom of over 20 leading experts, Keep Sharp makes the case that taking care of your brain is nasty business and simple lifestyle changes can help reduce your risk of Parkinson's disease, stroke, and other neurodegenerative diseases.

Inside, you'll learn:

• The real anatomy of focus — and why it's fragile

• The ways sleep, nutrition and emotional health influence your cognitive performance

• What your "Focus Index" score says about your state of mind

• Creating concise routines, settings, and rituals for your flow state.

• Why perfect is the enemy of clarity — and how to quantify true growth

• How to safeguard your mind like it matters — because it does

This is more than a productivity book.

It's a call to presence.

A mental, emotional, and, yes, spiritual reset.

Whether you are burned out or just want a clearer point of view, This book will help you recapture clarity that already exists.
