In a Culture Obsessed with Staying Young, We Ignore the Many Benefits of Aging

Every morning, millions of people wake up hoping to look, think and feel younger than they did yesterday. The anti-aging industry is worth hundreds of billions of dollars, promising everything from “miracle” supplements to gene therapies. Few people embody this pursuit more visibly than entrepreneur Bryan Johnson, whose quest to slow aging and achieve “immortality” has gained global fascination.

Johnson has meticulously documented countless treatments in his biohacking regimen, including cosmetic enhancements, stem cell therapies, a total plasma replacement and, most recently, even cloning his own cells. The message is clear: aging is something to defeat. But science tells a more complicated story.

While some aspects of functioning become less efficient with age, others remain remarkably resilient. Far from being a period of inevitable decline, research shows later life can bring a variety of unexpected strengths. Much of what we hear about aging focuses on what becomes harder.

Older adults often experience reductions in processing speed, working memory capacity, episodic memory retrieval and aspects of learning. These changes are real and important, particularly when they affect everyday independence or signal neurodegenerative disease, such as dementia. However, aging research increasingly shows that cognitive aging is not a one-size-fits-all.

Different abilities change at different rates, while some remain stable or improve well into later life. One of the clearest examples of beneficial change is the positivity effect. Research shows that older adults often pay more attention to, and remember, positive information compared to negative information.

This is not because they have poorer memory of negative events. Rather, this pattern of remembering seems to be linked to changes in motivation and priorities. As some psychologists suggest, older people become more focused on emotionally meaningful experiences because they perceive time as more limited.
