For more than 20 years, Dr. Daniel Amen, a renowned neuroscientist, has been working on improving brain efficiency. Amen studied more than 30,000 computed tomograms of the brain and is sure that his health is necessary for all aspects of a quality life. When the brain works correctly, then everything is fine with us, but if the brain is "sick," trouble begins. Improving brain function is therefore the most important first step to improving life. This book presents a step-by-step program to "turn" a good brain into an excellent one in just 15 days.
