Thank you for your comment! Regarding the brain part: " It is well established that the brain undergoes a “rewiring” process that is not complete until approximately 25 years of age. This discovery has enhanced our basic understanding regarding adolescent brain maturation and it has provided support for behaviors experienced in late adolescence and early adulthood. Several investigators consider the age span 10–24 years as adolescence, which can be further divided into substages specific to physical, cognitive, and social–emotional development." - so according to researchers, 24 years old is still within adolescence spectrum.
