My guest today is Dr. Brian Kennedy who is the Director for the Center of Healthy Aging at the National University of Singapore. He is also the former President and CEO of the Buck Institute of Research on Aging. Dr. Kennedy is well-known in the field of longevity & beyond and has been involved in critical aging research.  Dr. Kennedy's lab is working on different small molecules and natural products that could boost longevity.  In today's discussion, we spoke about the network concept of the hallmarks of aging, the longevity effects of natural products like Alpha-Ketoglutarate (AKG), Spermidine and Urolithin A, and why combining some of these supplements might not be prudent. We also spoke about comparing the different biomarkers of aging, what we can learn from the longevity of bats, and why basic science is important.   All platforms / Episode Show Notes + Timestamps: https://livelongerworld.substack.com/p/bkennedy  Sign up for Premium Subscriber Extensive Show Notes & Transcripts: https://www.livelongerworld.com/premium  Find the previous podcast episodes & subscribe to be notified: https://www.livelongerworld.com/podcast  Support on Patreon: https://www.patreon.com/livelongerworld  DR.
