Aging Well: At What Age Should the French Start Taking Action?

At what age should you really start taking care of aging well? A study by OpinionWay conducted for the French healthcare group Clariane, presented at the first Rencontres des gérosciences on January 14, 2026, offers a concrete answer to a question many people put off. Between persistent worry and a desire to act, it maps out a precise timeline of the milestones not to miss.

Widespread concern

The starting point is clear: 57% of French people say they are worried about their own aging, and 67% fear above all becoming a burden to their loved ones. Only 30% believe society today is prepared to meet this demographic challenge. This climate of concern doesn't, however, rule out a kind of will to act: 69% of respondents are convinced it's possible to slow down certain signs of aging.

Prevention: the French ready to change their habits

In practice, this conviction translates into strong intentions. 84% of respondents say they favor setting up regular prevention checkups, 77% say they are ready to change their lifestyle habits, and 59% are interested in using connected devices to track their health day to day. These figures echo an underlying trend already seen in other areas of digital life, much like the digital minimalism movement gaining ground among those looking to take back control of their habits.

The key ages for taking action, according to the study

One of the report's most concrete contributions is its timeline: aging well is prepared as early as one's thirties, and reinforced in one's fifties.

• Age 29: the average age considered ideal for adopting good lifestyle habits (diet, physical activity, sleep).
• Age 35: the point identified for starting to build savings dedicated to old age.
• Age 52: the age at which French people consider it relevant to draft their advance directives.
• Age 59: the ideal period to begin adapting one's home, an issue also reflected in the rise of intergenerational cohabitation as an alternative solution to isolated aging in place.

Technology, a still little-known ally

The report also examines the role of innovation. 84% of French people acknowledge that technology can improve quality of life with age, and 71% believe it can delay certain effects of aging. There is, however, still work to be done: 73% of respondents don't know what the term geroscience means—the discipline that studies the biological mechanisms of aging. Once the concept is explained, though, 63% to 64% find value in it. A pattern of gradual adoption of digital tools already seen elsewhere, particularly when personal health data comes into play, as shown by the debate surrounding the use of health data by artificial intelligence.

What the French expect from public authorities

Asked about the priorities to set collectively, respondents rank prevention and screening first (60%), ahead of equitable access to innovation (58%), training healthcare professionals in geroscience (51%), and funding research on aging (44%). An order of priorities that places individual prevention ahead of pure technological innovation.

Frequently Asked Questions

At what age should you start preparing to age well?

According to the OpinionWay study for Clariane, lifestyle habits are ideally worked on starting at age 29, while savings dedicated to old age are considered, on average, starting at age 35.

What is geroscience?

Geroscience is the scientific discipline that studies the biological mechanisms of aging in order to better understand, prevent, or delay its effects on health.

Do the French trust technology to help them age well?

A large majority (84%) acknowledges its value for quality of life, but trust remains conditional on education: nearly three-quarters of French people still don't know what geroscience covers until it's explained to them.
