THE DARK SIDE OF THE MIND
.
«I must say a word about FEAR. It is life's only true opponent. Only fear can defeat life. It is a clever, treacherous adversary, how well I know. It has no decency, respects no law or convention, shows no mercy. It goes for your weakest spot, which it finds with unnerving ease. It begins in your mind, always... So you must fight hard to express it. You must fight hard to shine the light of words upon it. Because if you don't, if your fear becomes a wordless darkness that you avoid, perhaps even manage to forget, you open yourself to further attacks of fear because you never truly fought the opponent who defeated you».

(Yann Martel, "Life of Pi") .

空气中是否有新型冠状病毒？还能开窗通风吗？来源：健康中国

新型冠状病毒可通过呼吸道飞沫传播。而飞沫传播距离很短，不会在空气中长期漂浮。从这个角度讲，在日常通风环境下，空气中一般不会有新型冠状病毒。所以建议每天至少两次开窗通风，是降低感染风险的有效措施，但是提醒大家，注意保暖。（中国疾控中心传染病处研究员 冯录召）
