过了52岁?你的脾气可能变大

    Britons find being older than 52 is nothing to laugh about because that's the age when they start becoming grumpy（脾气坏的）, according to a survey on Friday.
    The poll of 2,000 Britons found those over 50 laughed far less than their younger counterparts and complained far more.
    While infants laughed up to 300 times a day, that figure had fallen to an average of six laughs by teenage years and only 2.5 daily chuckles¹ for those over 60, the survey for cable TV channel Dave found.
    One reason for the decline in mirth might be the lack of joke-telling skills. The study found the average Briton only knows two jokes.（本文由在线英语听力室整理编辑）
