How old or young can you be?

Age can vary widely, as it ranges from newborns who are just hours old to individuals who are over a hundred years old. There is no strict limit to how young someone can be, as even a fetus in the womb can be considered "young." Conversely, people's experiences and maturity can make them feel younger or older than their chronological age. Ultimately, age is just a number that can reflect different stages of life.
