An interviewer question to the interviewee! Do you live to work or work to live?

Most of the interview questions are very psychological, interviewers ask some questions intentionally just to check your mind, emotions & mental stability. Of course everyone on earth "works to live" inclusive of these interviewers but these interviewers want to hear you say the "unrealistic" (i live to work) in view of having a "positive attitude" towards work while some of them would expect you to say "i work to live". I would personally answe this way, " I am a very hardworking person who is ready to do all it takes to positively contribute to the welfare & succes of the company if i am aavailed with this opportunity"
