What will people die of 100 years fromnow?If you think that is a simple question,you have not been paying attentionto the revolution that is taking place in bio-technology(生物技术).With the help of newmedicine,the human body will last a very long time.Death will come mainly fromaccidents,murder and war.Today’s leading killers,such as heartdisease,cancer,and aging itself,will become distant memories.

In discussion of technological changes,theInternet gets most of the attention these days.But the change in medicine canbe the real technological event of our times.How long can humans live?Humanbrains were known to decide the final death.Cells(细胞) are the basic units ofall living things,and until recently,scientists were sure that the life ofcells could not go much beyond 120 years because the basic materials ofcells,such as those of brain cells,would not last forever.But the upper limitswill be broken by new medicine.Sometime between 2050 and 2100,medicine willhave advanced to the point at which every 10 years or so,people will be able totake medicine to repair their organs(器官).Themedicine,made up of the basic building materials of life,will build new braincells,heart cells,and so on—in much the same way our bodies make new skin cellsto take the place of old ones.

It is exciting to imagine that the advancein technology may be changing the most basic condition of human existence,butmany technical problems still must be cleared up on the way to this wonderfulfuture.
