A frank, funny exploration of the anti-aging movement and what staying young really takes -- and means. A bootcamp in Utah in 118ʻ heat. A raw food diet. Hypnotic suggestions. A team of crack computer scientists who can age -- and de-age -- a face with the click of a mouse. The World Convention on Anti-Aging Medicine in Las Vegas (headlined by Suzanne Somers). These are just a few of the stops Lauren Kessler makes on her journey to reverse time from the inside out. At this moment, one in three Americans are entering midlife and many are wondering 'How did I get to be this old?' Plenty will turn to miracle creams, injections, fillers, and surgery to reverse the hands of time, but Kessler investigates the largely unexplored side of antiaging: what it takes to be younger, not just look younger. Guided by both intense curiosity and healthy skepticism, a sense of adventure, and a sense of humor, she investigates America's youth obsession and decides, on a very personal level, what to do about it.
