What Your “Age” Says About You

Imagine, for a moment, that you had no birth certificate and your age was simply based  on  the way you feel inside. How old would you say you are?

Like your height or shoe size, the number of years that have passed since you first entered the world is an unchangeable fact. 1.

Scientists are increasingly interested in this quality. They are finding that our “subjective  age” may be essential for understanding the reasons why some people appear to be energetic as they grow old — while others fade.

2. It is now well accepted that people tend to mature as they get older, becoming less extroverted ( 外 向 的 ) and less open to new experiences. These personality changes are often considered more obvious in the people with older subjective ages.

However, those who feel younger than they really are also become more reliable and less neurotic ( 神 经 质 的 ) as they gain the wisdom that comes with greater life experience. But it doesn’t come at the cost of the energy and vigor of youth. It’s not true that having a lower subjective age leaves us frozen in a state of permanent immaturity.

Feeling younger than your years also seems to come with a lower risk of depression and greater  mental  wellbeing as  we age. 3. Most people felt about eight years younger than their actual chronological age (实际年龄). But some felt they had aged — and the consequences were serious. Feeling between 8 and 13 years older than your actual age resulted in an 18-25% greater risk of death over the study periods, and greater disease burden — even when you control for other demographic ( 人 口 学 的 ) factors such as education, race or marital status.

4. However old you really are, it’s worth questioning whether any of those limitations are coming from the within.

A.It also means better physical health.

B.One of the most interesting aspects of the research has explored how subjective age interacts with our personality.

C.Some studies have explored the potential physical consequences of this difference.

D.These findings can give us all a view of the way our own brains and bodies endure the passing of time.

E.But everyday experience suggests that people often don’t experience ageing the same way.

F.Many researchers are now trying to study how this knowledge might help us live longer.
