1 . 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 was possible in the past. “There is a great effort so that people can live from 120 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 aging 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 Poon, director of the University of Georgia Gerontology Centre. “At present people who could get to that point are not in good health at all.”

2 . People have speculated (思索) for centuries about a future without work. Some imagine that the coming work-free world will be defined by inequality: A few wealthy people will own all the capital, and the masses will struggle in a wasteland. A different prediction holds that without jobs to give their lives meaning, future people will simply become lazy and depressed.
But it doesn’t necessarily follow from findings like these that a world without work would be filled with dissatisfaction. Such visions are based on the downsides of being unemployed in a society built on the concept of employment. In the absence of work, a society designed with other ends in mind could provide strikingly different circumstances for the future of labor and leisure.
These days, spare time is relatively rare for most workers. “When I come home from a hard day's work, I often feel tired,” says John Danaher, a lecturer at the National University of Ireland, adding, “In a world in which I don’t have to work, I might feel rather different — perhaps different enough to throw himself into a hobby with the enthusiasm usually reserved for professional matters.”
Daniel Everett, an anthropologist (人类学家) at Bentley University studied a group of hunter-gathers in the Amazon called the Piraha for years. According to Everett, while some might consider hunting and gathering work, hunter-gatherers don’t. “They think of it as fun,” he says. “They don’t have a concept of work the way we do.”
Everett described a typical clay for the Piraha: A man might get up, spend a few hours fishing, have a barbecue, and play until the evening. Does this relaxing life lead to the depression and purposelessness seen among so many of today’s unemployed? “I’ve never seen anything like depression there, except people who are physically ill,” Everett says. While many may consider work necessary for human life, work as it exists today is a relatively new invention in the course of human culture. “We think it’s bad to just sit around with nothing to do,” says Everett. “For the Piraha, it’s quite a desirable state.”
