Question 7 of 433
Is longevity science real, or is it marketing?
The short answer
Both. The laboratory science is real and exciting. Most of what is sold to consumers is far ahead of it.
Here is the honest scorecard as of late 2026. In mice, we can extend life with several drugs. In humans, we have no pill, infusion, or procedure proven to extend life in healthy people. Not one. What we have in humans are: early biological signals, clocks that move in the right direction, and a long list of ordinary medical treatments (blood pressure control, cholesterol lowering, vaccines, cancer screening) that absolutely do extend life and that nobody makes videos about.
This year alone taught the field humility more than once. A drug that powerfully lowers a dangerous cholesterol particle failed to prevent heart attacks in its big trial. A celebrated cancer blood test missed its main goal. You will read about both. Good science includes disappointment. Marketing never does.
