When does a boy become a man? Puberty too young, 18 workable, adulting principle preferred

Puberty: too young — can't drive, drink, work most jobs, live on own, still fully dependent on parents, not legally adult. 18: a legal definition that works but creates muddy zones in youth groups mixing 14 and 18 year olds. Independence/adulting: preferred principle — when someone steps into adult responsibilities, regardless of exact age. Varies by culture (a 16-year-old farmer vs. 19-year-old in the city). Mike leans toward the adulting principle, somewhere around 18-19, but acknowledges uncertainty.
