The unavoidable truth is that death only exists in the living world. I will die at some point but I will never experience death consciously - I will only be dead to others. This fact creates a strong bond between the two phenomena 'life' and 'death'.
We can't escape death and it is always there because we know that it will arrive at some point. This is the reason why we should not ignore it. We have to accept it to fully live life.
