About this course
Two people born the same year can be a decade apart inside. That gap is measurable, and unlike the calendar, it moves.
You will meet what biological age actually means and what is worth measuring, how much of ageing responds to behaviour and how much honestly does not, the four processes sitting behind most age related disease and why they always arrive together, muscle as the organ that decides independence, and why the same few markers repeated beat one comprehensive panel.
Six readings, each with a short check. Free, and yours to take in any order.
