Unlike chronological age, or the number of years a person has been living, biological age should reflect how well a person's bodily systems are working. Someone with a higher biological age has a higher risk for age-related diseases, such as cancer or dementia, than a person with a younger biological age. While some AI clocks look at epigenetic markers, others focus on other features, like the pitch and pace of people's voices, to calculate a biological age. We recently asked our readers if they would trust such AI tools to measure their biological age. Over 170 people responded, with 44%...
