Retirement is the stage in life when a person stops working full-time, usually after reaching a certain age or after completing a specific number of years in their career. This transition allows individuals to enjoy their free time, pursue hobbies, or spend more time with family and friends. Many people plan for retirement by saving money in accounts like 401(k)s or IRAs to ensure financial stability during this period. During retirement, individuals may also choose to engage in part-time work or volunteer activities, which can provide social interaction and a sense of purpose. Additionally, retirees often explore new interests, travel, or take classes to learn new skills. Overall, retirement is a time for relaxation and personal fulfillment after years of work.
