In general, people are living longer now.

[Yosarian]

A few words:

I find myself unable to write clichés. It is an immense effort for me to just put ready-made phrases down in my writing. I detest myself for trying to advance in a philosophical argument and then to cut in the middle due to confine space. I try to connect the topic with the knowledge that came from the books I have read. Is it a bad thing? There is no doubt that I divert from the subject however, is it still acceptable?

In general, people are living longer now.

Who is the “absurd man” in Camus’s essay “The Myth of Sisyphus”? The French author argues he is, i.e. the character of the work, the restless spirit who has come to realise that all being is deprived of meaning. In his essay, Camus quotes Dostoevsky – a Russian’s existentialist pioneer. Nevertheless, the characters of both these authors (Kirilov in Dostoevsky’s work and an anonymous man whom Camus calls The Absurd Man) struggle with the knowledge of life being a meaningless void.

However, they both believe in the magnanimity of human spirit and the ability of the human soul to triumph in demeaning circumstances. Both Camus and Dostoevsky are humanists. Not any less important are Camus’s contributions in favor of the abolishment of the death penalty in France which are broadly discussed in his essay “Reflections on the Guillotine”.

My intentions with the above examples are to illustrate that life is worth fighting for, as the cliché goes, and finding meaning in the whole ado is a matter of personal, conscious, and in most cases painful effort. There is no comfort in any of this, only knowledge.Thus far we understand that life, its quality and continuance are of paramount importance to the last century’s greatest minds.

It doesn’t strike us that scientists today focus on improving on the above features of life. The human life has become the most highly-regarded value of our society today. As a result in recent years we have seen immense improvements in all realms of science closely related to health care. Day by day we witness bloodless operations; we go to the dentist less afraid than ever; we take vitamins and work out to keep our bodies fit. We have roofs over our heads; heat and hot water are omnipresent. The home of the 21st century has turned into an impregnable fortress of well-being. Less people starve, we fight against injustice, conclude treaties which have economical or social benefits for society as whole. The world of today is less hostile, thus more determined to look after the prosperity of the race. To be honest about it, it’s a global world that we live in. If the question of the 20th century was “Is there any meaning in life, or are we all doomed to live in absurdity and after it to peter out in oblivion?” today the credo has shifted to “My only regret is that I couldn’t live longer, that I didn’t have time to give more.”

In conclusion I argue that, though it may seem rather philosophical, the only meaning of life can be in this to contribute to our race as whole. Our modern, sane society has long come to realise this. Hence, it focuses on improving on human’s life for the sole reason that if an individual is intelligent and well-educated he will come to the same conclusion. Every single life pays off for itself. Every existence is worth it, and meaningful – if we choose it to be.

Of course your writing deserves a 5, but I think the TOEFL grader might give you a 1 based on "questionable responsiveness to the task" or a 0 based on "rejects the topic"
I am not an official TOEFL grader, so this is just my opinon
