According to a new US study, couples who expect their children to help care for them in old age should hope they have daughters because they are likely to be twice as attentive overall.

The research by Angelina Grigoryeva, a sociologist at Princeton University, found that, while women provide as much care for their elderly parents as they can manage, men do as little as they can get away with and often leave it to female family members. Her analysis of the family networks of 26,000 older Americans concluded that gender (性别) is the most important predictor(预示物) of whether or not people will actively care for elderly parents.

In a paper being presented at the annual conference of the American Sociological Association in San Francisco, she concludes that simply having a sister makes men statistically likely provide less care.

Using data from the University of Michigan Health and Retirement Study, a study which has been tracking a cross-section of over-50s for the last decade, she calculated that women provide an average of 12.3 hours a month of care for elderly parents while men offer only 5.6 hours.

“Whereas the amount of elderly parent care daughters provide is associated with limitations they face, such as employment or childcare, sons’ caregiving is associated only with the presence or absence of other helpers, such as sisters or a parent’s spouse(配偶),” she explained.

“Sons reduce their relative caregiving efforts when they have a sister, while daughters increase theirs when they have a brother.”

“This suggests that sons pass on parent caregiving responsibilities to their sisters.”

In the UK, the 2011 census(人口普查) showed that there are now around 6.5 million people with caring responsibilities — a figure which has risen by a tenth in a decade.

But many are doing so at the risk of their own health. The census showed that those who provide 50 hours or more of care a week while trying to hold down a full-time job are three times more likely to be struggling with ill health than their working counterparts(相对应的人) who are not carers.

There’s a whole lot of things that people fill their stomachs with. Some of them keep people alive. Some of them taste good to people. Some of them help people win pie-eating contests. Alcohol does none of these things. Why do people keep drinking it? And what does it do once it gets to their stomachs?

There are all kinds of alcohol molecules (分子), but the one that people most often pour down their throat is ethanol (乙醇). Ethanol is very tiny and it dissolves in water, so it gets into all sorts of places that it’s not supposed to. Alcohol heads for the digestive system. Because it dissolves in water, it can get into the water in the bloodstream. Because ethanol, to a certain extent, can pass through cell membranes(膜). It can go almost anywhere. It spreads through the muscles, and is sweated — unmetabolized(未经新陈代谢的) and whole — through the skin. It gets into the heart. It even takes a walk through the brain, and this is the secret of its powers.

Alcohol depresses the nerves, and the nerves affect almost every area of the body. Enough alcohol makes people sleep, so people who become unconscious choke on their own vomit (呕吐物). Most worryingly, enough alcohol can shut down those parts of the brain just like any other parts. People become unconscious and their brains simply forget to breathe.

Alcohol is broken down in the liver. Alcohol doesn’t destroy the liver, but products that the liver breaks the alcohol into do cause damage. A glass of wine per day can not do any harm. Instead, it can prevent heart attacks or can make someone functionally young. And it is kind of nice to know that sometimes, relaxation and cheer can be bottled. All that’s needed is to take care how much alcohol is let into a person’s brain.
