Do you ever think that your mind is stuck in a different era? Maybe, you are 20-something with an old soul or someone in their 50s with youthful energy. The mental age does not always match your actual age and tells a lot about how you think. It refers to the level of cognitive ability, emotional maturity and intellectual development you exhibit.
