Yes, it is possible for someone to become more introverted as they get older, even if they were previously extroverted. Personalities can change and develop over time as a result of various factors such as life experiences, social and cultural influences, and individual preferences.
For example, a person who was extroverted in their youth may find that their social priorities and interests change as they grow older, leading them to become more introspective and preferring quieter, more solitary activities. Additionally, life events such as loss, trauma, or illness can also cause a shift towards introversion as a coping mechanism.
It’s important to note that personality traits such as introversion and extroversion are not absolute and can exist on a spectrum. It’s entirely possible for someone to exhibit both introverted and extroverted behaviors at different times in their lives or in different social situations. Therefore, it’s important not to make assumptions about someone’s personality based solely on their behavior in one setting or period of their life.
