这星期忙得透不过气来，竟把文法翻译科原本已非常技术性的教材弄得更複杂，最后要向学生致歉，笑说自己可能脑闭塞。

　　我跟其他学生分享自己“脑闭塞”的一天，并借题发挥，鼓励他们就这话题撰写文章。调皮的Y世代学生说可能我是“老闭塞”，毕竟我的年纪可以当他们的母亲了。学生们就Ageing, brain disease, dementia, memory loss, confusion及neurological disorders的议题撰写了精彩的文章，其中有几位建议我怎样把脑袋保持年轻不老。

　　I think Carol should train her brain more fast by playing video games with us. Playing video games need lots of brain power, we play video games at least 6 hours every day and see how smart and fast we are. Carol might have delirium, dementia or Alzheimer's disease or memory loss problems in her nervous systems because she works too hard. We are not sad for her because we will grow old one day and experience the same. We hope she works lesser and play more.

　　撇除文法上的错误及学生认为我真的是老及脑闭塞，我是欣赏他们用上丰富的词彙。我除了更正学生的文法错误也给了他们回应：Thanks for your concern of my brain health. Keeping the brain active with new mental activities help prevent brain damage. Yet, I'd rather playing real-life sports than playing video games. A healthy life both physically and mentally could be the best defence against the changes of an ageing brain. Time goes faster as I get older. I cannot manage what goes on outside, but I can control what goes on inside.

　　"Disorder"作名词使用，主要指混乱、动乱、暴乱、凌乱及杂乱无章。也经常被组织成compound noun（複合名词）使用。例如：mental disorders, psychological disorders, psychiatric disorders, public disorder。

　　要做到“老而不衰”实在不易。在我开始踏入中年，更体会到运动及健康饮食的重要。Physical exercises support the spirits, and keep the mind vigor.　　A healthy diet improves cognitive function and mood. These health benefits help us stay focused on our own performance.
