雾霾和吸烟，该担心哪个？
<p>最近看了个<span word="Ted">Ted</span>演讲，一位在中国行医的美国医生为大家讲述从一个医者的角度如何看待北京的雾霾问题，他提到在全球，第一大死因是心脏疾病，而在中国大家非常担心的食品安全问题和空气质量问题从数据的角度来看，其实有点掩人耳目，因为有更重要的事情人们忽略掉了。造成心脏问题的原因第一名是中国人的饮食盐分和脂肪太高，远比地沟油的威胁要大，北京平均的<span word="PM">PM</span>2.5水平相当于每人每天吸烟六分之一支，而中国每两个男人就有一个人抽烟，这比雾霾吓人的多。所以真正需要做的是少油盐的饮食和不吸烟，而不是食品安全和雾霾，后者也要去掉，但排序是靠后的。</p><p>1. <span word="Don">Don</span>’<span word="t">t</span> <span word="quit">quit</span>, <span word="except">except</span> <span word="for">for</span> <span word="smoking">smoking</span>.</p><p>永不放弃，除了戒烟以外。</p><p>2. <span word="N">N</span>95 <span word="is">is</span> <span word="a">a</span> <span word="standard">standard</span>, <span word="it">it</span> <span word="filters">filters</span> 95% <span word="of">of</span> <span word="what">what</span> <span word="you">you</span> <span word="breath">breath</span> <span word="in">in</span>.</p><p>口罩上的<span word="N">N</span>95是个国际标准，过滤掉你吸入的95%的空气。</p><p>3. <span word="Food">Food</span> <span word="safety">safety</span> <span word="and">and</span> <span word="air">air</span> <span word="pollution">pollution</span> <span word="are">are</span> <span word="distracting">distracting</span> <span word="us">us</span> <span word="from">from</span> <span word="the">the</span> <span word="real">real</span> <span word="problem">problem</span>.</p><p>食品安全和空气污染有点让我们跑题了。</p><p>4. <span word="Go">Go</span> <span word="dancing">dancing</span> <span word="with">with</span> <span word="your">your</span> <span word="grandparents">grandparents</span> <span word="in">in</span> <span word="the">the</span> <span word="park">park</span>, <span word="go">go</span> <span word="run">run</span> <span word="on">on</span> <span word="the">the</span> <span word="outside">outside</span>.</p><p>广场舞快要统治世界了，这是北京的一个美好的传统，这样其实有益健康，当然，还有跑步。</p><p>5. <span word="Wear">Wear</span> <span word="a">a</span> <span word="mask">mask</span> <span word="when">when</span> <span word="it">it</span>’<span word="s">s</span> <span word="bad">bad</span>, <span word="but">but</span> <span word="keep">keep</span> <span word="jogging">jogging</span> <span word="and">and</span> <span word="biking">biking</span> <span word="outside">outside</span>.</p><p>空气不好时也要跑步骑单车，只不过戴上口罩就好了。</p>
