Robot

There is no such thing as reason to live. If anyone has put such thing as a reason to live it is because he is distracted from nature and has lost the way to be in it. No animal has a purpose in life. And no human inherently does. It is been brought by abstract thinking and sometimes we get lost in its ways. You are just a robot that gets an input and gives an output. And all in all, you do not get away from that approach. You do not lament a purpose or never inherently asked for one. You just get up and act. That is your nature. That is how you are programmed. How much a robot you constructed would lament a purpose, to that extent you would lament the lack of a purpose and meaning in life.
