Speed of Thought
Our minds inevitably slow with age, but there's new evidence that it doesn't necessarily happen as early as once thought -- or feared. In a published study involving 1 million people who took an online cognitive test, older adults took longer to complete the test than younger participants, but their responses were more accurate.
As researchers noted, cautious thinking is still thinking. When they applied a statistical model to the data, they found that mental speed didn't actually dip until a person was in their 60s, contrary to previous studies that suggested the slowdown began as early as one's 20s.
