Shift Your Mind-Set

You're only as old as you think you are. In a new study in the journal Frontiers in Aging Neuroscience, older adults who said they felt younger had younger brains than their actual age. It may be that they felt young because they were neurologically healthier, but it may also be that having a younger mindset also helped them stay more active physically and mentally, which safeguards cognitive functioning, the researchers say. Bonus: With this attitude, you're also more likely to live longer too.
