If thoughts of your aging are making you anxious, researchers have found a cure. Not for the falling faces and sagging knees (you’ll need a doctor for that) but  new household economics study from Hiroshima University has found that financially literate people are less worried about growing old, mostly because they’re better at accumulating wealth. Let’s face it: knowing how you’ll care for yourself is comforting.

In response to the statistic proving 75 percent of Americans say they’re anxious about old age, researchers sent surveys to adults across the country who answered questions that tested their financial literacy, including basic calculation skills and understanding the pricing behavior of bonds. They also reported to what degree they felt anxious about life after turning 65 years old.

The group found that people with high financial literacy are significantly less anxious by way of accumulating assets, such as savings, bonds, and insurance. Less financially literate people, meanwhile, are less likely to have gathered enough assets to reduce anxiety, possibly because they rely more on social security income for assurance in old age.

This study is the first of its kind to examine how financial literacy influences anxiety about life in old age in the United States but last year, the same group conducted a similar study on Japanese people. Even with differences in cultural orientations and social norms between Japan and the United States, results from both countries appear similar among gender, education, and age. Financial literacy was higher among male, more educated, and older adults compared to female, less educated, and younger adults.

In other news, having a child and exercising regularly also helped ease anxiety.
