Insurance needs change throughout life, requiring regular policy reviews and adjustments. Young adults should focus on health and renters' insurance, while those starting work should consider employer-sponsored or independent coverage. Starting a family necessitates health, accident, and life insurance for dependents. Midlife may involve updating coverage after major life events. In retirement, understanding Medicare and long-term care is vital. Estate planning ensures wishes are honored and loved ones are cared for. Regular reviews can identify coverage gaps and savings.
