For centuries scientists have labored to identify and reverse the cause of aging, and now that effort has converged on one gland, one hormone, and one laboratory. The gland is the pineal, our body's natural timekeeper. The hormone is melatonin, the pineal's messenger. The laboratory is headed by one of the authors of this book. Drs. Pierpaoli and Regelson are the scientists credited with discovering the biological clock of aging, and now they explain to readers how to reset their biological clocks in order to live longer, healthier lives.The authors explain clearly, simply, and persuasively how melatonin works, how to use it, and what to expect when you do. In addition to their own internationally acclaimed work with melatonin and age-reversal, the authors address other important research currently under way around the world, including work that suggests melatonin is a safe, nonaddictive sleeping agent, can cure jet lag, boosts the immune system, increases our resistance to cancer and other diseases, lowers cholesterol, and can help relieve stress.
