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."

Why a Positive Attitude about Aging is Important

Our age beliefs can have a direct effect on our physiology. Elderly people who have been primed with negative age stereotypes tend to have higher systolic blood pressure in response to challenges, while those who have seen positive stereotypes demonstrate a more muted reaction. This makes sense: if you believe that you are frail and helpless, small difficulties will start to feel more threatening. Over the long term, this heightened stress response increases levels of the hormone cortisol and bodily inflammation, which could both raise the risk of ill health.

How your Attitude about Age affects your health

Recent findings suggest that age beliefs may play a key role in the development of Alzheimer’s disease. Tracking 4,765 participants over four years, the researchers found that positive expectations of ageing halved the risk of developing the disease, compared to those who saw old age as an inevitable period of decline. Astonishingly, this was even true of people who carried a harmful variant of the APOE gene, which is known to render people more susceptible to the disease. The positive mindset can counteract an inherited misfortune, protecting against the build-up of the toxic plaques and neuronal loss that characterise the disease.

Why Toilet Paper?

When people are told something dangerous is coming, but all you need to do is wash your hands, the action doesn't seem proportionate to the threat. The novel coronavirus is engendering a sort of survivalist psychology, where we must live as much as possible at home and thus must 'stock up' on essentials, and that certainly includes toilet paper. After all, if we run out of [toilet paper], what do we replace it with?

Stress can do a body good

Kelly McGonigal, a psychologist at Stanford University and the author of “The Upside of Stress”, helps people rethink stress by telling them that it is what we feel when something we care about is at stake. She asks them to make two lists: of things that stress them; and of things that matter to them. “People realise that if they eliminated all stress their lives would not have much meaning,” she says. “We need to give up the fantasy that you can have everything you want without stress.”

In 2012 a group of scientists in America looked back at the 1998 National Health Interview Survey, which included questions about how much stress the 30,000 participants had experienced in the previous year, and whether they believed stress harmed their health. Next, they pored over mortality records to find out which respondents had died. They found that those who both reported high stress and believed it was harming their health had a 43% higher risk of premature death. Those who reported high stress but did not believe it was hurting them were less likely to die early than those who reported little stress.

The study shows correlation, not causation. But since much stress is unavoidable, working out how to harness it may be wiser than fruitless attempts to banish it.
