Do you want to live another 100 years or more? Some exports say that scientific advances will one day enable humans to last tens of years beyond what is now seen as the natural limit of the human life span.
"I think we are knowing at the door of immortality (永生)." said Michael Zey, a Montclair State
University business professor and author of two books on the future. "I think by 2075____________________________ and that's a conservative estimate (保守估计的).”
At the conference in San Francisco, Donald Louria, a professor and author at New Jersey Medical
School in Newwark said advances in using genes as well as nanotechnology (纳米技术) make it likely
that humans will live in the future beyond what has been possible in the past. "There is a great push so that people can live from 120 to 1
80 years." He said. "Some have suggested that there is no limit and that
people could live to 200 or 300 or 500 years."
However, many scientists who specialize in aging are doubted about it and say the human body is just
not designed to last past about 120 years. Even with healthier lifestyles and less disease, they say failure of the brain and organs will finally lead all humans to death.
Scientists also differ on what kind of life the super aged might live. "It remains to be seen if you pass
120, you know; could you be healthy enough to have good quality of life?" said Leonard Poon, director of the University of George Gerontology Centre. "At present people who could get to that point are not in
good health at all."
