As a person starts accumulating more responsibilities to their families and workplaces, they tend to become more Agreeable--that is, less competitive, more cooperative, and more compassionate.

This can lead to less self-absorption and more absorption in their duties to other people. 

Gordon Allport's trait theory outlines 3 types of traits: Cardinal Traits (dominant traits/ruling passions), Central Traits (characteristics found (at least somewhat) in most or all people), and Secondary Traits (traits exhibited only on certain occasions).
