Study the following essay carefully and write a summary in about 80 words.

　　We continue to share with our remotest ancestors the most tangled and evasive attitudes about death， despite the great distance we have come in understanding some of the profound aspects of biology. We have as much distaste for talking about personal death as for thinking about it； it is an indelicacy， like talking in mixed company about venereal disease or abortion in the old days.

　　Death on a grand scale does not bother us in the same special way： we can sit around a dinner table and discuss war， involving 60 billion volatilized human deaths， as though we were talking about bad weather； we can watch abrupt bloody death every day， in color， on films and television， without blinking back a tear. It is when the numbers of dead are very small， and very close， that we begin to think in scurrying circles. At the very center of the problem is the naked cold deadness of one's own self， the only reality in nature of which we can have absolute certainty， and it is unmentionable， unthinkable. We may be even less willing to face the issue at first hand than our predecessors because of a secret new hope that maybe it will go away. We like to think， hiding the thought， that with all the marvelous ways in which we seem now to lead nature around by the nose， perhaps we can avoid the central problem if we just become， next year， say， a bit smarter. （246 words）

　　People dislike talking about death because they just like their predecessors still have the vaguest ideas of the issue. They talk about death only when million upon millions of people are killed in war. When they find only very few people die each time and the death rates are almost equal， they become very anxious， thinking that next time they themselves will meet their doom. Therefore， they fear very much. However， they have a hope that when they control nature， they can avoid death.（84 words）
