• 我们作为一种社会动物的生活，乃至于社会本身，是如何塑造了人类的大脑，而这种作用又如何反过来影响着我们的健康
• 长期经历孤独感的人，结果会造成身体上的伤害。
• 有一条最为重要的线索，表明在孤独与健康状况不佳之间，存在着某种生物学上的联系：许多疾病都与孤独有关。
• 加州大学洛杉矶分校(University of California, Los Angles)的史蒂夫•科尔(Steve Cole)表示：“我们知道，这些羞怯而孤独的人容易患上与炎症相关的疾病，并死于这些疾病。而压力荷尔蒙本该保护他们免受那种负面作用。”

• As my circle of Twitter friends began to grow the service became more useful for me, because I could learn more about what friends were doing or reading, and I could share the same with them.
• With reporting, the more friends you have the better, because if you put out a question to 800 people someone’s bound to have an answer; and if they don’t, they usually know someone who does.
• But on Twitter, if it’s hot news you’ll hear about it first. As humans are the best editors, it’s almost like a filter for what I need to know now.
• And if you have too many contacts, it’s most definitely a time suck for those who don’t have the discipline to stay away from it.

• 如今，在澳大利亚的超级市场，虽说仍然免费供应那种塑料薄膜袋，用来盛放所购的物品，但是顾客大都自觉抵制那些塑料薄膜袋，而是使用这种环保袋。各个超级市场都供应环保袋，每个环保袋定价九角九分澳币。
• 如今澳大利亚的妇女不以挎名牌皮包为荣耀，而是以拎环保袋为时尚。

• 悉尼有着强烈的环保意识。悉尼在申办2000年奥运会的时候，就响亮地提出“美丽悉尼，绿色奥运”的口号。

   

  悉尼是这么说的，也是这么做的。悉尼奥运组织者对环境保护的承诺包含五大部分，即能量循环，水资源回收，减小和避免浪费，污染处理以及重要的自然和文化景观保护。他们都做到了。

• 悉尼奥运会就连火炬也注意环保，采用容易充分燃烧的丙烷和丁烷的混合物作为燃料，减少有害气体一氧化碳的排放。

   

  悉尼市政府以及广大市民的强烈的环保意识，是值得其他城市学习的。

• Studies show that people who sleep between 6.5 hr. and 7.5 hr. a night, as they report, live the longest.
• Sleeping 8.5 hr. might really be a little worse than sleeping 5 hr.
• There have been many controlled studies in the U.S., Great Britain and other parts of Europe that show that an insomnia treatment that involves getting out of bed when you're not sleepy and restricting your time in bed actually helps people to sleep more
• It is in fact a more powerful and effective long-term treatment for insomnia than sleeping pills.

• While technology saves us the burden of remembering endless details, it also adds to our memory problems
• Memory works best when it interconnects. We create neural pathways in our brains as we connect a new piece of information with sensory details, recollections and knowledge -- forming a meaningful memory that we can easily retrieve.
• Another problem with technology is the obvious way that it interrupts us. Details are locked into our memories when we pay careful attention to them. That makes them more easily retrieved as well.
• We also have to admit that technology removes some of the mental discipline that every generation before us had to practice. We may be weakening ourselves over time because we don't have to do the work of memorizing information, navigating roads or keeping track of upcoming events now that digital devices handle those tasks for us
• Be sensitive to when you function best, and perform more challenging mental tasks during that time. You shortchange your abilities if you overload yourself with studies, work or competing obligations exactly at the time of day when you are at the lowest ebb.
• Writing supports memory. Yes, writing things down provides a helpful reminder. But it has also been found that the effort involved helps us organize our thoughts. Taking notes, making a list, drawing up an agenda, penning a letter, or keeping a diary stimulates the sort of thinking that is good for memory.
