Does refusing to act your age delay aging?

In a UK study, researchers found "people who thought old age began earlier were more likely to have had a heart attack, to be suffering from heart disease or be in poor physical health generally when they were followed up six to nine years later."

Becca Levy of The Yale School of Public Health "followed more than a thousand people who were at least 50 at the time. She found that people who had positive ideas about their own ageing (who agreed with comments such as "I have as much pep as last year" and who disagreed that as you get older you get less useful) lived for an average of 22.6 years after they first participated in the study, while the people who felt less positively about ageing lived for just 15 years more on average."

Claudia Hammond writing for BBC Future suggests "People who think old age starts later in life may be more conscious about their health and fitness and therefore take active steps to stay in better shape. They think they are younger and so behave in younger ways, creating a virtuous circle."
