SCIENCE

This is the science of aging, decoded for women in midlife. Every article on the Science page is grounded in peer-reviewed research and sourced from the world’s leading experts in healthy longevity. We cover the biology, the interventions, the emerging evidence, and what it means for how you actually age. Every claim is cited and every conclusion is one we’d trust with our own health.

  • Let’s say that person being 50 is 50 biologically, which means that’s the normal, it’s the average. Then lowering the biological age with lifestyle for example-eating patterns, quality of food, especially physical activity, managing sleep-you can biologically lowering…by roughly three to four years I would say easily.
