London:  Women usually start thinking that they are growing older at the age of 29, which is half the age of men who are struck by the ageing agonies at 58, a study has revealed.

A quarter of women said that they feel old as soon as they spot their first grey hair whereas men tend to think the same only when they can no longer perform in the bedroom.

The study by Avalon Funeral Plans found 10 percent of women said they feel old when they think their once-youthful skin has started to sag. A further 50 percent said they feel youthful until their "assets" start sagging.

And three percent said behaving like their mother was a definite sign of old age.

Two-thirds of men feel old only when they could no longer perform well in the bedroom.

 Psychologist Cary Cooper from Lancaster University said, "In our society the attractiveness of women is quite important. Men don't have to be good looking but, for some reason, it's important for women to look presentable."
