What is why are older brothers so protective?

Older brothers often feel a natural protective instinct towards their younger siblings, especially sisters. This protective behavior may stem from a variety of reasons, including a sense of responsibility to keep their siblings safe, a desire to be a positive role model, and a need to demonstrate their masculinity or strength. Additionally, older brothers may have witnessed or experienced difficult situations that heightened their protective instinct, such as bullying, family conflict, or dangerous situations. Overall, the protective behavior of older brothers can be seen as a positive trait, as it demonstrates a strong sense of empathy and responsibility towards those they care about.
