It is said that time waits for no man, but biologically speaking some people are barely ageing at all while others are speeding through their lives at the rate of three years every 12 months, scientists have found.
For the first time researchers have developed a test which reveals not only biological age but how fast people are growing old.
这现象首次引起研究人员关注 , 从而开发出了一种测试技术，用于测定人的生物学年龄，找到快速衰老原因。
And the results are startling. In a group of 38-year-olds, the scientists discovered that some had the same physiology as a 30-year-old while others were closer to 60.
The researchers from a range of institutions including Kings College London and Duke University in the US, believe it could explain why some people look far older than their years, while others appear to hardly age from year to year.
“We are now at a point where we can quantify biological ageing in young people, “ said Dr Andrea Danese, Senior Lecturer in Developmental Psychobiology and Psychiatry at Kings College London.
“And for the first time we can see how fast they are ageing. The people who had the oldest biological age were growing old the fastest.
“If we know that we can think about changing diets or making lifestyle changes when it is early enough to do something about it.
