6. With a team of colleagues at Tokyo National University, he setabout measuring brain volumes of a thousand
    people ofdifferent ages and varying occupations.
    7. Computer technology enabled the researchers to obtainprecise measurements of the volume of the front and
    sidesections of the brain, which relate to intellect (智能) and emotion, and determine the human character.
    8. Contraction of front and side parts as cells die off was observed in some subjects in their thirties,but it was still
    not evident in some sixty and seventy-year-olds.
    9. The findings show in general terms that contraction of the brain begins sooner in people in thecountry than in

    10. White collar workers doing routine work in government offices are, however, as likely to haveshrinking brains
    as the farm worker, bus driver and shop assistant.

    7、計(jì)算機(jī)技術(shù)幫助研究人員獲得人腦前部和側(cè)部的準(zhǔn)確體積，這是與人的智能和情緒有關(guān)的部分，而且也決定人的性格特點(diǎn)。
    8、有的人(大腦)前部和側(cè)部的收縮——隨著細(xì)胞的死亡——在三十多歲時就能被觀察到了，但是也有些人直到六七歲依然不明顯。
    9、研究結(jié)果表明在農(nóng)村的人大腦收縮基本上比城市里的人要早。
    10、在政府部門從事簡單重復(fù)工作的白領(lǐng)也像農(nóng)場工人、公共汽車司機(jī)和商店職員一樣大腦細(xì)胞容易收縮。
