“Results indicate that complete retirement leads to a 5-16 percent increase in difficulties associated with mobility and daily activities, a 5-6 percent increase in illness conditions, and 6-9 percent decline in mental health, over an average post-retirement period of six years. Models indicate that the effects tend to operate through lifestyle changes including declines in physical activity and social interactions. The adverse health effects are mitigated if the individual is married and has social support, continues to engage in physical activity post-retirement, or continues to work part-time upon retirement……. Retiring at a later age may lessen or postpone poor health outcomes for older adults, raise well-being, and reduce the utilization of health care services, particularly acute care.”
