Now she's ahead of the curve again -- conquering the mayhem, myths, and misunderstandings associated with aging. After all, if you can decide your weight, why not your age? Scientists and doctors have identified six major age inciters: metabolism, damaged macromolecules, epigenetics, inflammation, stress adaptation, telomeres. The 6 Keys presents an ageless health, fitness, and beauty plan that addresses all six of them -- and gets them working for you instead of against you. Empowering and rigorously researched, The 6 Keys outlines powerful lifestyle interventions, dietary guidelines, exercise plans, and vanguard strategies for cultivating mindfulness that restore and protect human performance, keeping you fit, healthy, and beautiful for life.
