A recent study found that Gen Xers reach their peak mental performance between the ages of 55 to 60. According to the research, various traits such as conscientiousness, emotional stability, and moral reasoning improve with age. However, overall mental functioning begins to decline after age 65, accelerating further after 75.
The study used a weighted index combining 16 dimensions of mental functioning and found that peak performance occurred between 55-60 years old. This discovery suggests that Gen Xers are in their prime mentally.
