Published in The New York Times, cardiologist Eric Topol discusses how advances in aging science are shifting the focus from reversing aging to predicting and preventing major age-related diseases. While experimental approaches like cell reprogramming or anti-aging drugs remain uncertain, new tools, such as genetic analysis, biological aging clocks, and AI-driven health data—may soon help doctors forecast an individual’s risk and timing of diseases like cancer, heart disease, and Alzheimer’s. The goal is to extend healthspan, enabling earlier intervention through monitoring, lifestyle changes, and preventive care.
