what is a life? Is it just the act of existing or is there more to it? Some would argue that life is defined by your experiences.
Things like memories or feelings like happiness is what defines life. Would it be right to then assume that if you don't feel happy or don't have any good memories that you are not alive? Because an existance of only pain and suffering can hardly be called a life, can it?
It is true that life can't only be happiness and fun it also has to involve some moments of sadness and hurt, but if you have one without the other are you really living?
I would argue that at the point when your life is only sorrow and hurt and you see no end to it then you are no longer living.
Because a human being that don't think they can ever feel happiness again might aswell be dead.

Is there really any difference if the mind is dead and numb and the body carries on then isn't it better if the body also gives up?
Or can there actually still be hope after the mind has given up.
I feel that this is a matter that differs from person to person so will we ever have a solid answer to the question?
We may never know and maybe just maybe we are better of not knowing.
