Can aging actually be reversed — or is most of “anti-aging” still hype? In this solo FAQ episode, Dr. Hillary Lin breaks down what longevity science can and cannot say yet about biological age, cellular reprogramming, senolytics, NAD+ supplements, and lifestyle.

The short version: some biological markers and disease-risk factors can improve, and some lab/animal research is genuinely exciting. But that is not the same as a proven consumer protocol to reverse aging, live forever, or make every supplement worth buying.
