A new study finds that aging does not necessarily lead to decline, with nearly half of people over 65 showing improvements in physical or cognitive performance over time. The results also show that those with a positive outlook on aging are more likely to experience these gains.
The research, led by Becca Levy of Yale University, followed thousands of participants for years and found that improvement is not rare—it is nearly as common as decline.
Details
Researchers used data from the Health and Retirement Study, tracking indicators such as walking speed and cognitive function for up to 12 years. The findings showed:
- Nearly half of participants recorded measurable improvement.
- Positive attitudes toward aging increased the likelihood of improvement.
Meanwhile, negative stereotypes about aging remain widespread. Many people still believe cognitive decline is a normal part of getting older, even though most older adults do not suffer from significant impairment or dependency.
Experts say aging can bring added advantages, including better judgment, experience, emotional intelligence, and even higher life satisfaction. Having a sense of purpose—through family, volunteering, or hobbies—is also linked to better health and activity levels.
The study highlights what researchers call a “snowball effect”: a positive mindset encourages healthy behaviors such as exercise and social engagement, which in turn reinforce both mental and physical well-being.
What’s next?
Researchers are now focusing on interventions that can reshape how people view aging, treating mindset as a modifiable factor that may directly influence health and longevity.
