Practically and very pessimistically to speak we live for death.
Never mind my rude reply here.
But in a more positive note we live to feel, to experience, to love, to care, to be cared for and to live in the minds of our nearest ones even after we are gone from this world. To prosper in our life, to experience and be where we wish to be and the happiness that we can spread around us makes life worth living even more then we can live for. After we are born here we may live with a positive and caring attitude to pass every day of our life in the praise of Almighty for whom we are here. Its all in our mind and aspiration that can make our life meaningful for a better cause in this world. We can live close to the meaning of our birth here by trying to spread love and compassion for the needy ones around us.
Thank you for this is an interesting question again.
