What would happen if you never smiled?

If you never smiled, it could affect your social interactions and relationships, as smiling is a universal sign of friendliness and approachability. People might perceive you as unfriendly or unapproachable, which could lead to misunderstandings and isolation. Additionally, not smiling can impact your own mood and mental health, as the act of smiling is associated with the release of endorphins and can promote feelings of happiness. Overall, a lack of smiling could create a cycle of negativity both for you and those around you.
