Have you ever wondered what the absolute limit of human life is? While legends tell of people living for centuries, modern science points to a hard-coded expiration date: around 125 years. In this episode, we dive deep into the groundbreaking Hayflick Limit, the biological clock inside our cells that dictates why we age and die.

We'll explore the science of cellular aging, telomeres, and the research that changed our understanding of longevity forever. We also investigate the fascinating and controversial stories of the world's oldest people, from Jeanne Calment (122 years) to the incredible legend of Li Ching-Yuen, a man said to have lived to 256.

Join us as we separate scientific fact from historical myth and explore humanity's timeless quest for the elixir of immortality. Is 125 the end of the line, or can we push the boundaries? Tune in to find out.
