Puberty is not an illness - it's time to see it differently! Puberty has a bad reputation. However, insights from brain research present a more nuanced picture. Sarah-Jayne Blakemore is one of the leading researchers in this field worldwide and vividly explains that typical teenage behavior is driven by the changes the brain undergoes during adolescence. We finally understand why teenagers behave so strangely, why they misjudge risks, and why they are constantly glued to their smartphones. This is a relieving and enlightening read for all parents and educators, contributing to a more objective understanding. After all, youth is a time of opportunities and possibilities: we should celebrate it. It tells us fundamental truths about who we are.
