How old is too old to be living with parents?

I'm 19 now... that means I'll be 22 by the time I move out. Is that too old?

A real man moves out of his parents house at the age of 18, directly after grasduating high school.
To live with your parents after legally attaining your independence is the mark of a boy, not a man.

Just look at RedCream, for example...53 years old and still living in his parents basement. Could there be any harder FAIL than that....I think not..
