How much of a biological-age shift reflects perimenopause? FSH, estradiol and AMH track ovarian aging, offering context rather than a whole-body age score.

For biological age, strength versus cardio is a false choice: combining them supports both muscle strength and aerobic fitness. If you disagree, we would like to hear the strongest version of the other side.
