Step-by-step explanation:
Many middle-aged adults tend to feel young, and that in terms of basic personality traits, they perceive important similarities between their present selves and their younger selves.
This implies that, as people age, they increasingly incorporate age-stereotypes into their self-view, such that, they tend to see themselves as being younger, even though, they are getting older.
Various research suggests that many middle-aged adults tend to report being younger than their real age, for example they tend to claim to be 20% younger, and this phenomenon increases with age. By claiming a younger subjective age, many middle-aged adults believed, that there is various benefits for health and well-being available to them.
