He talked about the physiology of what happens to the body with stress, exercise, sleep and boy, these were enlightening. I started a few months prior to reading this book seeing the effects of stress, exercise, sleep on weight loss and I came to similar conclusions that Singh did. It really helped validate what I had already learned, but he was able to talk about it more scientifically.
The book is well-written. It also talks about what happens to our bodies when we don't manage stress, get enough sleep, get adequate exercise, and if our diets are poor. He goes into the pros/cons here.
He gives ways to develop brain longevity by fixing the prior and supplementation through vitamins/minerals/natural supplements. It's a great insightful book and life changing.
The 5 principles of brain longevity are: 1. The brain is flesh and blood; 2.The powers of the brain are virtually limitless; 3. The brain is capable of infinite joy and pleasure; 4. The brain has a plastic quality and can renew itself; 5. Much about the brain remains a mystery.
Part I covers the discovery of brain longevity therapy, Part II explains how the brain works and Part III deals with designing a brain longevity program. This includes the brain longevity diet, nutritional therapy (including the role of vitamins A, B, C and E, minerals like magnesium, selenium and zinc, amino acids like phenylalanine, glutamine, methionine, arginine and tryptophan, substances like co-enzyme Q10 and tonics like gingko biloba, phosphatidyl serine, acetyl-l-carnitine, ginseng, DMAE and green tea.
This section also includes methods of stress management, mind/body exercises and the assessment of the efficacy of various medicines like deprenyl.
Khalsa's book is highly recommended to people who wish to take responsibility for their own health with special emphasis on maintaining the highest levels of cognitive ability. It concludes with a Resources and Referrals section and a thorough index. I also recommend the book Mind Boosters by Ray Sahelian, an examination of natural substances that promote cognitive longevity.
