The term "retirement years" refers to a period in an individual's life when they are no longer actively working and have retired from their career. This typically occurs after reaching retirement age, which varies by country but is generally around 65 years old. During these years, individuals may engage in leisure activities, travel, pursue hobbies or interests, spend time with family and friends, or volunteer in their community. The "retirement years" are often seen as a time of relaxation and enjoyment after many years of hard work and dedication to one's career.
