If you're lucky enough to live into your 90s, how well will your brain hold up? You may have an edge over people who got there ahead of you, a new study hints.
Researchers found that on tests of mental abilities, a group of 95-year-old Danes scored better than a group born 10 years earlier who were tested at about the same age.
In a standard simple test, for example, 23 percent of them scored in the highest category, compared with 13 percent of the earlier-born group. Out of the 30 questions and tasks, members of the later-born group averaged two more correct responses than the earlier-born group did. The results were released Wednesday by the journal Lancet.
