When we’re young, we want to be older, but as we get older, we wish we were young again. A new study published in the journal Psychology and Aging shows some benefits and risks for both age groups. Researchers at the University of California, San Diego studied 62 adults in their twenties and 54 adults over 60. The researchers surveyed both groups to assess anxiety, depression, loneliness, and overall mental well-being. Participants also took a number of cognitive tests while their brain activity was tracked using EEG studies. The researchers found that the young adults experienced far more anxiety, depression, and loneliness than the older adults. But while the older adults had higher levels of well-being, their cognitive function was lower.
