Can you really lower your biological age – how do the celebrities do it?

Yes: several people (e.g. Bryan Johnson, David Sinclair, Benedikt Keck) publicly document that their PhenoAge or DunedinPACE is measurably below their chronological age. Common levers: consistent sleep (Cristiano Ronaldo: 5×90-min cycles), strength and endurance training, plant-forward nutrition, targeted supplementation (NMN/NAD+, omega-3, vitamin D, spermidine) and stress regulation. Details per person on the individual protocol pages.
