Being an Adult

[Jeremiahcp]

A concept people generally use to stroke their own ego and pretend they are superior to others.

You want to know what makes someone an adult? It is biology and it happens to everyone.

In the last decade, a growing body of longitudinal neuroimaging research has demonstrated that adolescence is a period of continued brain growth and change, challenging longstanding assumptions that the brain was largely finished maturing by puberty [1–3]. The frontal lobes, home to key components of the neural circuitry underlying “executive functions” such as planning, working memory, and impulse control, are among the last areas of the brain to mature; they may not be fully developed until halfway through the third decade of life [2]. This finding has prompted interest in linking stage of neuromaturation to maturity of judgment. Indeed, the promise of a biological explanation for often puzzling adolescent health risk behavior has captured the attention of the media, parents, policymakers, and clinicians alike. Although such research is currently underway, many neuroscientists argue that empirical support for a causal relationship between neuromaturational processes and real-world behavior is currently lacking [4].
