Youth Emancipation in Spain

The Spanish Government is so worried about the number of young adults still livingwith their parents that it has decided to help them leave the nest.

Around 55 percent of people aged 18-34 inSpain still sleep in their parents' homes,says the latest report from the country's state-run Institute of Youth. To coax (劝诱) young people from their homes, the Institute started a \解放)\findingrooms and jobs.

Economists blame young people's family dependence on the precarious (不稳定的)labor market and increasing housing prices. Housing prices have risen 17 percent ayear since 2000.

Cultural reasons also contribute to the problem, say sociologists (社会学家). Familyties in south Europe - Italy, Portugal and Greece - are stronger than those in middle andnorth Europe, said Spanish sociologist Almudena Moreno Minguez in her report \

\bodyaround which theirprivatelife is organized\

In Spain - especially in the countryside, it is not uncommon to find entire groups ofaunts, uncles, cousins, nieces and nephews (外甥/侄子) all living on the same street.They regularly get together for Sunday dinner.

Parents' tolerance is another factor. Spanish parents accept late-night partying andare wary of setting bedtime rules.

Surprised by a Miracle

I had been working in the trauma unit at a local hospital for about a year. You getused to families thinking that a \昏迷) patient is moving their hand or doingsomething that they were asked to do. \it often it's\callous （麻木不仁的) toit.

On this particular night during visiting hours, my patient's wife came ~n. I had takencare of him for several nights I was very familiarwith his care and what he was able to do.Actually,he didn't do anything. He barely moved at all, even when something wouldobviously hurt him, such as suctioning (抽吸)

6 / 12

His wife was very short, about 5 feet tall. She had to stand on a stool to lean overhim, so that she could see his face and talk to him. She climbed up on the stool I spoketo her for a few minutes, and then stepped out to tend to my other patient. A few minuteslater, she came running out of the room. In an excited voice, she said, \

I immediately thought that it was probably her imagination, and that he had notactually done it on purpose. He had been there about a month atthe time and had nevermade any movements on purpose. I asked her what had happened and she said, \

This led me to another train of questioning. \did he let go when you asked himto?\

I went into the room with her, not really believing that I would see anything differentthan I had always seen. But I decided that it would be better to pacify (抚慰) her than tomake her think that I didn't believe her or that she was somehow mistaken.

She asked him to squeeze her hand, which he did.

I said, \that whenhe finally did let go, I really still didn't believe that he had done it on purpose.

So, I said, \

Well, hmm, this was starting to get my attention. I looked at him, his face stillsomewhat swollen (肿胀的) and his eyes still closed. \out your tongue!\I said. Hedid it. I almost fell on the floor. It was the first time I had ever seen anyone \

Slowing Aging: Way to Fight Diseases in 21st Century

A group of aging experts from the United States and the United Kingdom suggestthat the best strategy for preventing and fighting a multitude of diseases is to focus onslowing the biological processes of aging.

\diabetes,heart disease, Alzheimer's disease (早老性痴呆病) and Parkinson's disease (帕金森氏病)-will soon become less effective if we do not determine how all of these diseases eitherinteract or share common mechanisms with aging,\says S. Jay Olshansky, professor ofepidemiology at the University of Illinois at Chicago School of Public Health and seniorauthor of the commentary.

Middle-aged and older people are most often impacted by simultaneous butindependent medical conditions. A cure for any of the major fatal diseases would haveonly a marginal impact on life expectancy (预期寿命) and the length of healthy life,Olshansky said.

The authors suggest that a new paradigm (模式) of health promotion and diseaseprevention could produce unprecedented social, economic and health dividends forcurrent and future generations if the aging population is provided with extended years ofhealthy life.

They note that all living things, including humans, possess biochemical mechanismsthat influence how quickly we age and, through dietary (饮食的) intervention or geneticalteration, it is possible to extend lifespan to postpone aging-related processes anddiseases.

Further research in laboratory models is expected to provide clues to and deeperunderstanding of how existing interventions, such as exercise and good nutrition, maylead to lifelong well-being.

The authors also propose greatly increased funding for basic research into the \cellular (细胞的) and physiological changes that drive aging itself.\ %underrecognized by most of the scientific community,\thehealth-research decision-makers to allocate substantial resources to support anddevelop practical interventions that slow aging in people.\

An increase in age-related diseases and escalating health care costs make this thetime for a \

Olshansky and colleagues contend that modern medicine is already heavily investedin efforts to extend life, and they argue that a fresh emphasis on aging
