WASHINGTON: Assessing how and why people age differently has long eluded doctors and scientists, particularly when there are no obvious explanations such as illness or history of injury.
But a team of researchers at Duke University, Harvard University and the University of Otago believe they could have solved the riddle by developing a brain scan-based tool they say can "tell how fast someone is ageing", be that physically or cognitively.
