Dr. Mike Evans, a semi-retired University of Toronto professor of family medicine, says retirement plans should include health, purpose and relationships alongside savings. He urges retirees to stay mentally and physically active rather than slip into a passive routine.
Evans cites tests in which retirees often showed a verbal-memory dip around 14 months after retirement, and MIDUS data linking withdrawal from meaningful challenges with faster cognitive decline. The Framingham Heart Study, which followed more than 4,300 adults for nearly 40 years, found midlife exercise cut dementia risk by 41%; a separate study reported cognitive improvements after 10–20 minutes of moderate-to-vigorous activity a day.
Evans says retirement can take away the structure and social connections tied to work and family, so people may need to choose new sources of purpose. A meta-analysis associated a stronger sense of purpose with lower risks of cardiovascular events and death from any cause. He says roughly one in three people report social isolation by age 65; he also cites links between isolation and higher depression and dementia risks, and a trial in which expanding a friend group could delay dementia by about five years.
