医生应该允许病人有充裕的时间描述自己的身体症状和内心痛苦，唐突地打断可能在刹那间丧失

本文是环保类话题，关键词是geo-engineering。全文如下：A former Government chief scientist once told me that we should always have a Plan B ready in case Plan A doesn’t work – or doesn’t happen. He was speaking in relation to the possibility of “geo-engineering” the climate if it becomes obvious that global warming is beginning to tip irrevocably towards a potentially dangerous state.He could only say this once he was out of office of course because the official Government view at the time – as it is now – was that “there is no Plan B” in relation to climate change, that the only conceivable way of avoiding dangerous global temperature increases in the future is to curb the production of greenhouse gas emissions now.Geo-engineering is defined as the deliberate, large-scale intervention in the Earth’s climate system in order to limit undesirable climate change, but it is seen by many as a technical fix too far. At its most outlandish, geo-engineering envisages putting giant mirrors in space to deflect incoming solar radiation, but it also includes more benign interventions, such as solar powered “artificial trees” in the desert for soaking up carbon dioxide in the air.Despite the official view of there being no Plan B, however, last week’s fifth report by the Intergovernmental Panel on Climate Change (IPCC) has placed geo-engineering firmly on the agenda – even if the scientific panel rather denigrates the idea as probably unworkable and potentially dangerous. Nevertheless, for some critics of geo-engineering the mere mention of the concept in such an official and high-profile publication is enough to see red.Indeed, the Canadian-based ETC Group of environmentalists, perceived a Russian-led conspiracy to subvert the IPCC process. Russia had insisted on the addition of geo-engineering to the report and it is Russia where many geo-engineering projects are being tested, the ETC Group claims.Before getting carried away with the inclusion for the first time of geo-engineering in an IPCC report, it is worth pointing out that the panel emphasises the inherent flaws of the proposals to counter rising temperatures. Deflecting sunlight with artificially created white clouds over the oceans, for instance, would do nothing to prevent the acidification of the oceans and, if it had to be stopped for any reason, global surface temperatures would soon rise again even higher than before.In short, if we rely on a technical fix to combat climate change, rather than addressing the root problem, we could become addicted to the illusion that all is well when, in fact, all that we are doing is delaying the inevitable, while increasing the risk of some serious unintended consequences, which history tells us are never far away from big engineering proposals of this kind.Take for instance the relatively small-scale geo-engineering project to divert the rivers running into the Aral Sea of the former Soviet Union. Half a century ago the Aral Sea was the fourth largest lake in the world with a thriving commercial fishery, but by 2007 it had declined to about 10 per cent of its original size, with fishing boats stranded in the middle of a toxic salt pan.Soviet scientists diverted water from two rivers running into the Aral Sea to irrigate fields of cotton and other crops. But in the end they created a barren, dusty landscape where once there was a sea filled with wildlife. Toxins and salt blown from the Aral’s parched basement even threatened the very crops that the project was meant to generate.So when some people talk about the possibility of “fixing” the climate with technological interventions rather than cuts in carbon dioxide emissions, let’s not forget history. Perhaps HM Government is right: there is no Plan B.Talking of carbon dioxide, I have just returned from an interesting visit to the Czech Republic where health tourism, rather than being frowned upon, is positively encouraged.What has this got to do with carbon dioxide, you may ask Well one of the more curious, if not bizarre “medical” treatments you can buy is a dip in a dry bath of carbon dioxide. For 20 minutes or so you bathe everything below your waist (fully clothed) in an atmosphere of “natural” carbon dioxide pumped from underground sources.It is said by those who sell it to cure a range of conditions and even acts like a dose of Viagra. Strictly in the interests of science I volunteered. I intend to publish my findings in a peer-reviewed scientific journal – that is if I can find one prepared to overlook my limited set of data points.

A new study has been carried to test the role of story telling in lowering blood pressure. Dr. Thomas Houston, a professor of the University of Massachusetts Medical School, led a group of scientists that researched how pre-recorded videos of hypertension (高血压) patients' talking about their medical histories helped another group of patients with high blood pressure to control their condition over several months.

Houston was surprised by their studies that suggested that communication can be a powerful tool in medicine. They showed that those who had had similar experiences, when talking to someone with a similar background, could help change their behavior to become healthier. Hypertension is difficult to control, since it is dependent on diet, exercise and mental state. Medical treatments with drugs, and lifestyle therapies(疗法) have been relatively ineffective because people find it hard to follow those medical requirements.

In the test, his team carefully chose their story-tellers from 230 members of a patients' community with whom they could most easily relate. Next, they divided their study population into two groups. One received three interactive DVDs containing the tellers' stories of their experiences in living with and treating their hypertension. The other were given educational discs on an unrelated health topic. The study volunteers reported that they had listened to the DVDs, and after three months, those who heard the stories of the hypertensive patients lowered their blood pressure.

While the study did not address how the story-telling influenced the patients' behavior, Houston doubts that watching patients of similar backgrounds who had a similar medical experience helped to motivate them to seek medical help to their hypertension. They found that after six months the difference in blood pressure between those who watched the story-tellers and those who observed the unrelated videos remained, suggesting that the story-telling continued to have an effect.
