"Do you know that your heart is under attack every day? Your heart is under attack, not from the obvious dangers of poor diet and lack of exercise, but from hidden assailants in your environment. This is what this book is all about. I tell the story of my life-long friend Leslie's sudden cardiac arrest at the age of 63. By the end of this book, you will know what unfortunately Leslie did not. You will know how to use green space and your own heart rate numbers to: avoid these hidden threats; protect your heart; know when your heart is in danger and what to do about it. I wrote this book so that what happened to Leslie does not happen to you -- so that you can live your best life possible." - from Author
