A new poll finds that nearly a third of Americans over 50 provide regular care to an adult relative or friend with a health issue or disability, highlighting the need for increased awareness of existing programs such as adult day programs and respite care. Many caregivers face financial stress and don't know about or use these resource...
A 45-year study found that early life leisure-time physical activity is linked to better work ability in late adulthood. Higher levels of activity throughout the lifespan contribute significantly to work ability, with a dose-response association observed in late adulthood.
