Episode notes
Epigenetics plays a critical role in health and aging by potentially preventing issues like cancer through the shutdown of certain genes. It serves as a more accurate measure of biological age than chronological age, as individuals can exhibit significant differences in health despite sharing the same birthdate. Cellular reprogramming, a field focused on reversing aging by reverting cells to their earlier, more primitive states, has shown promising results in animal studies. However, this approach raises concerns about the long-term risk of cancer, emphasizing the evolutionary strategy to guard against cellular misbehavior during critical life stages.
