Life seems to always be attempting to stop death, is intelligence another attempt at completely preventing it..
Life, not human life.. get over your freaking selves.
For my the purpose of life is to do the mission that God gave to you. While you are living in earth you must do a good thing so that if you die you may say that you life is not like a trash that don't have a good purpose or important. Do what you think is right. Do what is good.
