Ageing rates vary widely, says study

"The international research group followed 954 people from the same town in New Zealand who were all born in 1972-73. ( www.bbc.co.uk/news/health-33409604 )
The scientists looked at 18 different ageing-related traits when the group turned 26, 32 and 38 years old.

The analysis showed that at the age of 38, the people's biological ages ranged from the late-20s to those who were nearly 60."

"Prof Moffitt told the BBC: "Any area of life where we currently use chronological age is faulty, if we knew more about biological age we could be more fair and egalitarian."

So we keep telling them, but employers don't seem to listen, neither do journalists and fashion students.
