Sport or Spectacle Muhammad Ali is probably the most famous sports figure on earth: he is recognized on every continent and by all generations. The diagnosis of his illness (51) Parlonson’s disease after his retirement fuelled the debate about the dangers of boxing and criticism (52) the sport. That, plus his outspoken opposition (53) women’s boxing, made people wonder how he would react when one of his daughters decided to take (54) the sport. His presence at Laila’s first professional fight, (55) _, seemed to broadcast her father’s support. Of course Muhammnad Ali wanted to watch his daughter fight. The ring announcer introduced him as the "the greatest" and as he sat down at the ringside the crowd chanted. Twenty-one-year-old Laila’s debut fight was a huge success and there was as much publicity for the fight (56) her father’s fights once attracted. (57) , Laila’s opponent was much weaker than she was and the fight lasted just 31 seconds. Since then, Laila has won most of her fights by knocking out her opponent. "She knows (58) she’s doing, all fight, "said one referee about her. "She knows about moving well. You can see some of her dad’s moves." Laila Ali would rather not compare herself (59) her father. She prefers to make her own (60) . Her father supports her decision to enter the sport but he has not spared her the details of what can happen. Laila realizes that her father wants her to understand the (61) possible scenario to see (62) she still wants to go forward with it. She knows she’s going to get hit hard at times, that she may get a broken nose or a swollen face, but at least she is prepared for it. Laila’s decision to start boxing (63) her father’s struggle with the symptoms of Parkinson’s disease has of course sparked a mixture of debate and (64) . But Laila is a feisty and determined individual and it is that as much as her famous last name that has made her a magnet for worldwide media attention. Of course, the (65) on the boxing scene of a woman with her family history attracts even more questions about whether women’s boxing is sport or spectacle．

Retirement Brings Most a Big Health Boost The self-reported health of the newly retired improves so much that most feel eight years younger, a new European study suggests. This happy news was true of almost everyone except a small minority only 2 percent who had experienced "ideal" conditions in their working life, anyway. "The results really say three things: that work puts an extra burden on the health of older workers, that the effects of this extra burden are largely relieved by retirement and, finally, that both the extra burden and the relief are larger when working conditions are poor," said Hugo Westerlund, lead author of a study published online Nov. 9 in The Lancet. "This indicates that there is a need to provide opportunities for older workers to decrease the demands in their work out of concern of their health and well-being. " But of course, added Westerlund, who is head of epidemiology at the Stress Research Institute at Stockholm University in Sweden "not all older workers suffer from poor perceived health. Many are indeed remarkably healthy and fit for work. But sooner or later, everyone has to slow down because of old age catching up. " Last week, the same group of researchers reported that workers slept better after retirement than before. "Sleep improves at retirement, which suggests that sleeping could be a mediator between work and perception of poor health, "Westerlund said. This study looked at what the same 15,000 French workers, most of them men, had to say about their own health up to seven years pro-retirement and up to seven years post-retirement. As participants got closer to retirement age, their perception of their own health declined, but went up again during the first year of retirement. Those who reported being in poorer health declined from 19.2 percent in the year prior to retirement to 14.3 percent by the end of the first year after retiring. According to the researchers, that means post-retirement levels of poor health fell to levels last seen eight years previously. The changes were seen in both men and women, across different occupations, and lasted through the first seven years of not punching the clock. Workers who felt worse before retirement and had lower working conditions reported greater improvements as soon as they retired, the team found. Older workers usually get on very well with younger workers.
A Sunshade for the Planet Even with the best will in the world, reducing our carbon emissions is not going to prevent global wanning. It has become clear that even if we take the strongest measures to control emissions, the uncertainties in our climate models still leave open the possibility of extreme warming and rises in sea level. At the same time, resistance by governments and special interest groups makes it quite possible that the actions suggested by climate scientists might not be implemented soon enough. Fortunately, if the worst comes to the worst, scientists still have a few tricks up their sleeves. For the most part they have strongly resisted discussing these options for fear of inviting a sense of complacency that might thwart efforts to tackle the root of the problem. Until now, that is, a growing number of researchers are taking a fresh look at large-scale "geo-engineering" projects that might be used to counteract global wanning. "I use the analogy of methadone," says Stephen Schneider, a climate researcher at Stanford University in California who was among the first to draw attention to global warming. "If you have a heroin addict, the correct treatment is hospitalization and a long rehab. But if they absolutely refuse, methadone is better than heroin. " Basically the idea is to apply "sunscreen" to the whole planet. One astronomer has come up with a radical plan to cool Earth; launch trillions of feather-light discs into space, where they would form a vast cloud that would block the sun’s rays. It’s controversial, but recent studies suggest there are ways to deflect just enough of the sunlight reaching the Earth’s surface to counteract the warming produced by the greenhouse effect. Global climate models show that blocking just 1.8 per cent of the incident energy in the sun’s rays would cancel out the warming effects produced by a doubling of greenhouse gases in the atmosphere. That could be crucial, because even the most severe emissions-control measures being proposed would leave us with a doubling of carbon dioxide by the end of this century, and that would last for at least a century more. According to the first two paragraphs, the author thinks that______.
