Biological age: blood, DNA and longevity tests explained
The creator describes three ways to estimate biological age — blood-based calculators, epigenetic DNA testing and broader longevity services — and says results from different methods should not be compared automatically. [1]

Blood markers and phenotypic age in the description
The creator says one biological age number can come from very different types of testing. He describes blood-based biological age calculators and explains that phenotypic age uses a person's actual age plus nine common blood markers. According to the description, these markers relate to inflammation, blood sugar, kidney and liver function, and blood cell health.

DNA methylation, epigenetic clocks and telomere testing
The description also covers DNA methylation, epigenetic clocks and telomere testing as further approaches. The creator states that results from these different tests should not automatically be compared with each other. The description does not report any measured values, study data or accuracy figures for these methods.

Life Force service and physical function measures
The creator describes Life Force as a broader testing service with more than 50 biomarkers, an interactive dashboard showing a life score and biological age result, a 45-minute clinician consultation and personalized recommendations. He also mentions physical function measures such as walking speed, grip strength, balance and rising from a chair, and says he would focus on trends over time rather than chasing the youngest biological age number.
