According to the latest issue of the United States, "Journal of geriatric medicine," the quarterly report, the scientists found that despite the growing elderly physical aging, but their mental age younger than the average physical age of 13 years old, which is more mental age young men.

psychology professor at the University of Chicago Jackie Smith led the study.

they took time to assess the 6 years of age in 516 men and women aged over 70 found that mental age of these people are generally lower than physiological age, which are almost all men feel smaller than the actual age. Smith analysis, more women than men care about appearance than men and therefore mental age is closer to the actual age. This is not to say men do not mind getting older, but their assessment of life satisfaction are more factors, after the elderly is still able to accept new things.

researchers said that older age and mental health conditions. Younger people feel better health status, and poorer health status of the elderly, mental age and actual age is even more similar.
