Why do you think that many teenagers feel that they are so invincible?

Answer 1

Teenagers may think they are invincible because it helps them give confidence in themselves to get through anything, also if someone doubts something, they are more likely to not do it than if they beleived they could.

Answer 2

Teenagers often have immature frontal lobes, leading to impulsive behavior and a lack of consideration of consequences. Hormonal changes can also lead to feelings of invincibility and risk-taking behaviors. Additionally, limited life experiences and a desire to assert independence can contribute to a sense of invulnerability.
