Wow, now there is a lot of philosophy for what you said, means the life is eternal but it's not given us to waste it.
there is some reason behind why we are born, what is our purpose, don't you think this life is like an examination where we are testing in different ways?
think about it 
find the reason behind GOD making our bodies and sending us to earth i promise you if you found that it will change your life
