my point of view.

Immortality is wield by no man. It is an useless term for those incapable of seeing the truth. The truth about whether death is your friend or foe. To believe that death is your foe, makes you an optimist of life, that life brings you good. Those who believe that death is your friend, is an optimist of death, and can welcome it, due to it's the natural way of life.
To throw away death is like to throw away your own existance, when death gives you what you earn. Life gives you false views.
It does not matter to live long or short. Life doesn't matter at all. You gain something that you'll lose either way. To be optimistic or pessimistic, is the wrong sense of lifestyle. They give you nothing it owns you whether you want it or not. A neutral lifestyle makes it easier to make a life flow. Don't wish, because you'll lose it straight away.
Take life as it comes. Don't strife to high nor far, nor short if so too. Don't strife at all. Be a living object, then perish when time comes. Because; if you see something after this. Then you won't lose nor win at all. You will be perfect the way you were.
