Wellington: Scientists can now finally answer the question of whether you really are as old as you feel, say researchers in New Zealand. A new method to determine biological aging could be a breakthrough in therapies that slow aging and help prevent age-related diseases before they occur.


The international study tracked more than 1,000 people born in the South Island city of Dunedin in 1972-1973 from birth to the present, Xinhua news agency reported. A large number of health measures including blood pressure, white blood cell count, liver and kidney function were taken regularly along with interviews and other assessments.


The research team members from the US, Britain, Israel and New Zealand combined 18 biomarkers to determine whether people were aging faster or slower than their peers. Most study members were found to be clustered around one biological year per chronological year, but others were found to be aging as fast as three biological years per actual year.


Many were staying younger than their age. People aging more rapidly were less physically able, showed cognitive decline and brain aging, reported worse health and looked older. The ability to detect accelerated aging at an early stage paved the way for applying therapies that slowed aging and lessen age-related ailments.
