The provided text from the BBC outlines the sit-to-stand (STS) test, a simple 30-second assessment that reveals important aspects of an individual's strength, balance, and flexibility, and consequently, their overall health and aging. Doctors and researchers use this test to gauge the functional abilities of older adults, and studies suggest that lower scores can indicate a higher risk of falls, cardiovascular issues, and even mortality. The article details how to perform the test at home using a chair and timer, provides average score ranges by age group according to the CDC, and discusses how improving physical activity can positively impact one's STS performance.
