Longevity framing without reported results
The description frames the video around longevity and healthy aging and uses hashtags such as biological age, cell aging and anti-aging. It does not report a study design, sample, follow-up, measured outcome or numerical result. Whether biological age can be influenced is presented as a chapter question, not as an answered finding.
