"Lifespan" by David Sinclair

"Lifespan" by David Sinclair explores the science of aging, emphasizing that aging is a biological process influenced by genetic and environmental factors. Sinclair discusses how our cells age due to accumulated damage and declining function, but this process can be slowed or potentially reversed through lifestyle choices and emerging therapies. He highlights key areas like cellular repair mechanisms, such as sirtuins and NAD+ metabolism, and the potential for scientific advancements to extend healthy lifespan. Ultimately, Sinclair advocates for preventative approaches to aging, aiming to improve quality of life and longevity through a better understanding of our biology.
