You know, historically, there's been a strong belief that as we age, our physical and mental abilities decline.
A study out of Yale has really told us that that's for at least half the population.
So what they found is that nearly half of adults over 65 do improve physically, mentally or both over time.
They also found that people with the more positive attitudes about aging were the ones that were significantly more likely to show these gains just across the board.
So what they did is they analyzed data from 11,000 participants in the Health and Retirement Study, which is a federally funded long-term survey of older Americans.
During that period, 45% of these participants of the 11,000 showed improvement in at least one of the two areas examined.
