So, most of us have at least one biological weak spot, even if our overall aging profile looks fine on paper. For years, the conversation around muscle has centered on how you look or how you perform. This research suggests that the biological age of your muscle tissue may be one of the most meaningful signals of how long and how well you’ll live.
