This estimates how your lifestyle compares with what is known to support hormonal health, and expresses it as an age. It is a way of presenting habits, not a measurement of your body.
Nobody can determine your biological age from eight questions. What the score does is show which habits are working for you and which are working against you, in a form that is easier to act on than a list.
The factors included are those with the strongest evidence for influencing hormonal health across both sexes.
Sleep, because most testosterone is produced during it and disrupted sleep affects insulin, appetite and cortisol.
Body composition, particularly visceral fat, which converts testosterone to oestradiol and drives insulin resistance.
Resistance training, the single intervention that opposes age-related muscle loss.
Alcohol, which affects sleep architecture, liver hormone processing and recovery.
Stress, through its effect on the cortisol rhythm.
Diet quality, particularly protein adequacy and the pattern that supports stable blood glucose.
The number itself matters less than which answers pulled it in each direction.
A result older than your real age usually traces to one or two dominant factors rather than everything at once. Fixing the biggest one moves the number more than small improvements across the board.
The most common single driver is sleep, and it is also the one people most often treat as unfixable.
It does not measure hormones, and no questionnaire can. If you have symptoms, blood tests are what settle the question.
It is also not a biological age test in the scientific sense. Those use markers such as DNA methylation and are research tools rather than consumer products.
Treat this as a structured way of looking at habits, and use it as a baseline to repeat in three months rather than as a verdict.
