“人死不能复生”,这似乎是无可置疑的一条定则。然而,随着科学技术的进步,一些科学家对此提出了挑战。他们认为,许多人的所谓“死”,是因为现代医学对这些疾病无能为力,否则,他们仍有99％的希望活着。他们举例说,过去的很多致命的疾病,现在都可以治好,原因是科学技术进步了。基于这种认识,他们正在试验用低温冷冻的方法,将病死后的人体冷冻长期 “There is no way for people to die,” which seems to be an unquestionable rule. However, with the advancement of science and technology, some scientists have challenged this. They believe that the so-called “death” of many people is because modern medicine cannot do anything about these diseases. Otherwise, they still have 99% hope to live. For example, they said that many of the deadly diseases of the past can now be cured because of scientific and technological progress. Based on this understanding, they are experimenting with a cryogenic method that will freeze the human body after death.
