A three-day-week gets the best performance from workers aged over 40, a study has found.
一項(xiàng)研究發(fā)現(xiàn)，40歲以上的人如果每周上三天班，工作表現(xiàn)最佳。

Researchers found the cognitive performance of middle-aged people improved as the working week increased up to 25 hours a week.
研究人員發(fā)現(xiàn)，當(dāng)中年人每周工作時(shí)間達(dá)到25小時(shí)，認(rèn)知表現(xiàn)將有所改善。

However, when the week went over 25 hours, overall performance for the test subjects decreased as "fatigue and stress" took effect.

The report, which was published in the Melbourne Institute Worker Paper series, invited 3,000 men and 3,500 women in Australia to complete a series of cognitive tests while their work habits were analysed.
發(fā)表在《墨爾本研究院工人報(bào)》的這篇研究報(bào)告邀請(qǐng)了澳大利亞的3000名男性和3500名女性來完成一系列認(rèn)知測試，同時(shí)分析他們的工作習(xí)慣。

It was found those working 25 hours a week performed best while those working 55 hours a week showed results worse than retired or unemployed participants.
研究發(fā)現(xiàn)，每周工作25小時(shí)的人表現(xiàn)最佳，而每周工作55小時(shí)的人的測試成績比那些退休或待業(yè)的人還糟。

One of the three authors, Professor Colin McKenzie from Keio University told the Times: "Many countries are going to raise their retirement ages by delaying the age at which people are eligible to start receiving pension benefits. This means that more people continue to work in the later stages of their life.
該研究報(bào)告的三位作者之一、來自日本慶應(yīng)義塾大學(xué)的科林?麥肯齊教授告訴《泰晤士報(bào)》說：“許多國家都預(yù)備提高退休年齡，讓人們延遲領(lǐng)取養(yǎng)老金。這意味著更多人在中晚年還要繼續(xù)工作。

"The degree of intellectual stimulation may depend on working hours. Work can be a double-edged sword, in that it can stimulate brain activity, but at the same time long working hours can cause fatigue and stress, which potentially damage cognitive functions.
“智力被激發(fā)的程度可能取決于工作時(shí)長。工作是一把雙刃劍，既能夠刺激大腦活動(dòng)，同時(shí)過長的工作時(shí)間也會(huì)導(dǎo)致疲勞和壓力，并有可能損害認(rèn)知功能。

"We point out that differences in working hours are important for maintaining cognitive functioning in middle-aged and elderly adults. This means that, in middle and older age, working part-time could be effective in maintaining cognitive ability."
“我們指出了不同工作時(shí)長的區(qū)別所在，這對(duì)于保持中老年人的認(rèn)知功能具有重要意義。這意味著，在中晚年，從事兼職工作將能有效地保持認(rèn)知能力。”

The research comes amid moves to edge the British state pension age closer to 70.
研究發(fā)布正值英國計(jì)劃將法定退休年齡提高到將近70歲。

Currently for someone born in 1989, a state pension begins at the age of 68.
根據(jù)目前的法規(guī)，1989年出生的人要到68歲才能領(lǐng)到養(yǎng)老金。
