There is no age more dangerous than old age.

No one is so old that he cannot live yet another year, nor so young that he cannot die today.

Neither the universal return to life, universal resurrection, nor even death itself, have hitherto been the subject of knowledge or well founded judgement. For there would have been full, detailed investigations into the reasons and conditions that have given rise to the phenomenon. For most people, death appears to be an absolute, inevitable phenomenon; but just how unfounded is this conclusion is obvious from the fact that it is considered acceptable to talk about the opposite of death, about immortality, and even about resurrection; and it is talked about as a possibility, in circumstances where all sorts of sins prevail among people, and all sorts of calamities and evils, arising from the folly of nature. But if the coexistence of the one with the other is unthinkable, since the one excludes the other, then can one talk about the possibility of death where there is moral and physical sinlessness, where nature shows such a benign attitude both within and outside man, of the sort that is deemed possible when man's knowledge and control of nature are complete?

It is impossible that any thing so natural, so necessary, and so universal as death, should ever have been designed by Providence as an evil to mankind.

There is no such thing as a natural death: nothing that happens to a man is ever natural, since his presence calls the world into question. All men must die: but for every man his death is an accident and, even if he knows it and consents to it, an unjustifiable violation.

We are going to die, and that makes us the lucky ones. Most people are never going to die because they are never going to be born. The potential people who could have been here in my place but who will in fact never see the light of day outnumber the sand grains of Sahara.

How young can you die of old age?

But no matter what safety steps we take or what security precautions we adopt, our risk of death is not approximately – but exactly – 100 percent. There is no margin of error on the statistic.

If someone in going to die anyway without an operation, then you have nothing to lose by trying.

We are going to die, and that makes us the lucky ones. Most people are never going to die because they are never going to be born. The potential people who could have been here in my place but who will in fact never see the light of day outnumber the sand grains of Arabia. Certainly those unborn ghosts include greater poets than Keats, scientists greater than Newton. We know this because the set of possible people allowed by our DNA so massively outnumbers the set of actual people. In the teeth of these stupefying odds it is you and I, in our ordinariness, that are here.

Our bodies are full of unsuspected flaws, handed down it may be for thousands of years, and it is of these that we die, and not of natural decay. Till these are eliminated, or as nearly eliminated as possible, we shall never even know what true old age is like, nor what the true natural limit of human life is. The utmost limit now appears to be about one hundred and five years, but as each person who has got so far has died of weaknesses inherited through thousands of years, it is impossible to say to what number of years he would have reached in a natural state. It seems more than possible that true old age—the slow and natural decay of the body apart from inherited flaw—would be free from very many, if not all, of the petty miseries which now render extreme age a doubtful blessing. If the limbs grew weaker they would not totter; if the teeth dropped it would not be till the last; if the eyes were less strong they would not be quite dim; nor would the mind lose its memory.

If there's any illness for which people offer many remedies, you may be sure that particular illness is incurable, I think.

[N]ow we see eyes become dim and artificial aid needed in comparative youth, and teeth drop out in mere childhood. Many men and women lose teeth before they are twenty. This simple fact is evidence enough of inherited weakness or flaw. How could a person who had lost teeth before twenty be ever said to die of old age, though he died at a hundred and ten? Death is not a supernatural event; it is an event of the most materialistic character, and may certainly be postponed, by the united efforts of the human race, to a period far more distant from the date of birth than has been the case during the historic period. The question has often been debated in my mind whether death is or is not wholly preventible; whether, if the entire human race were united in their efforts to eliminate causes of decay, death might not also be altogether eliminated.

Death cannot be experienced either by the dead or the living.
