We don't need Big Pharma to keep us feeling young: we already have the tools. Greger breaks down the science of aging and chronic illness, and explains how to help avoid the diseases most commonly encountered in our journeys through life. Physicians have long treated aging as a malady, but getting older does not have to mean getting sicker: there are eleven pathways for aging in our bodies' cells and we can disrupt each of them. Greger presents simple, accessible, and evidence-based methods to preserve the body functions that keep you feeling youthful, both physically and mentally.
