Dear MEL School’s Topic Readers,
Ageing rates vary widely, says study
Is chronological age the best indicator for
how old a person is? How close is it to the person’s biological or mental age?
Imagine meeting old school friends after a
couple of decades. You’ll be surprised how different they look, including you.
Some look nearly as same as they were while others look so different that you might
even think they were their parents. You may agree that when people turn 50,
they surely look widely different. Some may look in their 40s and others look
60s. However, a new study has found that people seem to age at a speed much faster
or slowly than others even in their 20s or 30s.
Tracking nearly 1,000 New Zealanders, the
study found that at the age of 38, some people's biological ages ranged from
the late-20s to nearly 60. If people’s biological ages vary that much, should people
in the same chronological age be treated in the same way? For example, how much
medicine or calorie should be taken, how much exercise is recommended, what
sort of physical examination is appropriate and how much longer they should
work?
Enjoy reading and thinking of
chronological, biological and mental ages.
