Living At Home After A Certain Age

[Taualumna]

I know a guy in his early 30s who had moved back home. He is currently living in his parents' basement, but has his own entrance and a kitchen. Is this a good idea? How old do you think is too old to be living at home? Do you think it's more difficult for grown children of some cultures to be independent because they're expected to live at home until they marry? I certainly don't intend to be living with my parents when I'm 40.
