What two reasons does the author of what the brain says about maturity give to explain why brain development is not used to determine when adulthood begins?

Answer 1

The author notes that brain development does not determine adulthood because maturity encompasses more than just brain growth; it also involves emotional and social factors that influence decision-making and responsibility. Additionally, societal and cultural norms play a significant role in defining adulthood, which vary across different communities and time periods, making it difficult to rely solely on biological markers for such a complex transition.
