Dr. David Katz: Lifespan Clock, Bodies Destroying Themselves, & Evolution Selecting for Aging – 250

August 13, 2024

“My long-term goal is to model the pathways involved in human aging in order to develop therapeutic interventions. I organize an annual aging conference in the Midwestern United States with the dual goal of promoting the aging as an adaptation theory and promoting the aging as a disease mindset. The conference website is curing-aging.com.”
