Scientist proves better busy than doing nothing, research has found. Keeping the mind occupied with tasks—no matter how meaningless—keeps off negativeemotions, the study found. [2] However, the bad news is that humans seem born to be lazy in order to save energy, according to Professor Christopher Hsee, a behavioural scientist at Chicago University. [3] In a study 98 students were asked to complete two surveys. After they had completed the first they were made to wait 15 minutes to receive the next one. They were given a choice of either handing in the first survey nearby or at a more distant location they had to walk to. Whichever choice they chose, they received a chocolate bar. Two-thirds (68 per cent) chose to take a shortcut. Those who had taken the walk reported feeling happier than those who had stayed put. Prof Hsee concluded __________________ helped keep people happy. [4] He said the findings, reported in the journal Psychological Science, had policy guidance. 'Governments may increase the happiness of idle（闲散的）citizens by having them build bridges that are actually useless', he suggested. [5] At the individual level, he advised: 'Get up and do something. Anything. Even if there really is no point to what you are doing, you will feel better for it .' He added, 'By the way, thinking deeply or busy with self-reflection counts as keeping busy, too. You do not need to be running around—you just need to be busy, either physically or mentally.' 小题1:What is the purpose of the text?
