Claimed gap between biological and calendar age
The description states that biological age can differ from calendar age by up to 30 years. It gives an example of two people of the same calendar age with a 19-year biological difference and calls this normality when nothing is measured. These are claims made in the description, not results of a study presented there.

Four measurement methods named in the description
According to the description, the video explains four methods for determining biological age: the epigenetic clock after Steve Horvath and Morgan Levine, the PhenoAge blood panel, the sit-to-stand test from a Brazilian long-term study, and VO2max. VO2max is described as the strongest single longevity predictor according to a JAMA meta-analysis. The description does not report how these methods were compared or what values they produced.
