Longevity: Hope, Hype, and Science with Dr . Bill Lawrence

What does it truly mean to live longer—and how can we separate promising longevity science from exaggerated claims? In this episode of the Ageless and Timeless Podcast, Michele Hughes welcomes back longevity researcher and biogerontology scientist Bill Lawrence, PhD, for an evidence-focused exploration of biological aging, healthspan, and peptide bioregulators. Dr. Lawrence explains the important distinctions between lifespan, healthspan, and biological longevity. He also discusses how researchers use biomarkers such as telomere length, epigenetic testing, pace of aging, and organ-specific biological age to evaluate potential longevity interventions. Drawing upon his work with the scientific legacy of Professor Vladimir Khavinson, Dr. Lawrence introduces Khavinson Peptide Bioregulators—short, organ-specific regulatory peptides studied for their potential influence on gene expression, cellular repair, and age-related functional decline. He explains how these compounds differ from popular synthetic peptides and why the two categories may serve very different purposes. The conversation also examines the evidence behind today’s most talked-about longevity interventions. Dr. Lawrence separates approaches that may improve general health or reduce disease risk from those he believes meet a more rigorous standard for influencing biological aging.
