Modern scientists divide the process of dying into two stages clinical or temporary death and biological death. Clinical death occurs when the vital organs, such as the heart or lungs, have stopped functioning, but have not suffered permanent damage. The organism can still be saved. Biological death occurs when changes in the organism lead to the “breaking up” of vital cells and tissues. Death is then unchangeable and final.Scientists have been seeking a way to prolong the period of clinical death so that the organism can remain alive before biological death occurs. The best method developed so far involves cooling the organism, combined with narcotic (麻醉) sleep. By slowing down the bodys metabolism (新陈代谢), cooling delays the processes leading to biological death.To show how this works, scient
