This book is based on improving my health after i retired 2 years ago, as well as our roles as grandparents. Sitting home and not being active can really affect your mental and physical health. Referencing a quote from the Greek Philosopher, Plato "necessity is the mother of invention" I applied it to my current state of well-being, and knew that it was necessary for me to re-invent myself in my senior years. I think you will find this book helpful as there are many facts as well as personal trials, and solutions to having a healthy mind, body, and soul.
