Aging Isn't Wear and Tear, It's a Programming Problem w/ Dr. Adeel Khan

What if aging is not simply the result of wear and tear, but a biological process we may eventually be able to measure, influence and partially reprogram? In this episode of Adding Years, we are joined by Dr. Adeel Khan, a physician working at the intersection of regenerative medicine, longevity and emerging biotechnology. Dr. Khan explains the differences between functional medicine, regenerative medicine and longevity medicine—and explores how these fields may converge as scientists learn more about the underlying biology of aging. The conversation covers: • Why aging may be viewed as a cellular “programming” problem • The difference between full and partial cellular reprogramming • How exercise, sleep and nutrition influence cellular function • What stem cells actually do inside the body • The differences between MSCs, Muse cells, PAC cells and exosomes • Why some regenerative treatments work differently from person to person • The potential—and uncertainty—surrounding follistatin gene therapy • How biological-age tests should and should not be interpreted • Why proteomics may offer a more detailed view of how the body is functioning • How specialized biological AI could help connect biomarkers to actionable health insights • Why the fundamentals of sleep, exercise, nutrition and stress management still matter—even alongside advanced longevity treatments The information provided in Adding Years: Your Roadmap to Longevity is for informational and educational purposes only and is not intended to replace professional medical advice, diagnosis, or treatment.
