Job Interview Gurus: "Tell me about yourself" how do you personally answer this question?

Going in for a final interview and the way I started off to answer this the first time around, I told them I was married and had a son, then I swiftly went into my work experience.

Any tips advice? Should I go straight to the point of work experience? I was kind of thinking it would set me a part from young adults and might make me seem more mature and kind of eliminates the possibility of me being the non punctual party type.

What’s your take?
