The Longevity Doctor's Prescription for a Healthier Life Dr. Ronald Primas, a 66 year old physician and pioneer in preventative medicine, has spent decades studying the science of longevity.
He has helped his patients cheat death – or at least slow it down – by focusing on small habits and a commitment to living a healthier lifestyle.
Primas' approach is built on the idea that chronic disease often begins years before the first symptom appears.
