i dont wanna grow up, im a jim beam kid

im a 25-year old boy. i'll readily admit that, and for any foreseeable future, i will consider myself a whatever-age-i-am-now year old boy.

my question is at what stage of life do people stop acting silly, juvenile, adolescent, etc, in regard to drinking and socializing?
does it depend on level of education? socioeconomic status? marital status?
being in my mid-20s, i dont feel super responsible or grown up, and i can tell you most of the people around me certainly arent that way either. but when does it become unacceptable to act like a college kid when you drink?
i mean if weird law school kids continue to act immature and irresponsible (read: awesome) well into their mid-20s, why should this stop any time soon for anyone?
i say lets devolve man. let the chips fall where they may. keep going to those parties, getting hammered, falling down and getting giant bruises that you dont remember getting, making out with anyone and everyone. whether im drunk or sober, you know im gonna be enjoying the ride, and i dont plan on growing up any time soon.
look for me -- ill be the one smacking asses, dragging from my beam-filled flask, and otherwise being awesome
