Do you want to live another 100 years or more? Some experts 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 knocking 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 we will see it and that's a conservative estimate (保守的估计)."
At the conference in San Francisco, Donald Louria, a professor at New Jersey Medical School in Newark 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 I20 to 180 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 ageing are doubtful 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 Pooh, director of the University of Georgia Gerontology Centre. "At present people who could get to that point are not in good health at all."

One of Britain's bravest women told yesterday how she helped to catch suspected (可疑的) police killer David Bieber -- and was thanked with flowers by the police. It was also said that she could be in line for a share of up to ￡30,000 reward money.
Vicki Brown, 30, played a very important role in ending the nationwide manhunt. Vicki, who has worked at the Royal Hotel for four years, told of her terrible experience when she had to steal into Bieber's bedroom and to watch him secretly. Then she waited alone for three hours while armed police prepared to storm the building.
