Comparison of energy drink
Coca-Cola Energy contains caffeine from naturally-derived sources, guarana extracts and B vitamins, and completely taurine-free.
Celsius is not recommended for people sensitive to caffeine, children under the age of 18, or women who are pregnant or nursing.
Taurine in Red Bull is produced synthetically by pharmaceutical companies, which guarantees highest quality standards.
Monster ingredients are not listed on the official website.
Taurine: According to the Mayo Clinic, taurine is an amino acid that's naturally found in a number of foods. It plays an important role in many of the metabolic processes but little is known regarding the effects of long-term supplemental use.
Guarana Extract: According to an April 2015 study published in Public Library of Science One, guarana is a plant native to the Amazon. The seeds contain about four times the natural caffeine in coffee beans, and when combined with caffeine from other sources, guarana provides additional stimulation.

Community-acquired pneumonia (CAP) is one of the most common infectious diseases and is an important cause of mortality and morbidity (發病) worldwide. Typical bacterial pathogens that cause CAP include Streptococcus pneumoniae, Haemophilus influenzae, and Moraxella catarrhalis. However, with the advent (出現) of novel (嶄新) diagnostic technologies, viral respiratory pathogens are increasingly being identified as frequent etiologies (病原) of CAP. The most common viral pathogens recovered from hospitalized patients admitted with CAP include human rhinovirus (鼻病毒) and influenza.

聲樂心理治療
小時候，時常不明白為何電視台有這麼多音樂節目。人長大後，便覺得香港的年青人心裡充滿空虛，成年人內心充斥唏噓。閱讀以外，音樂正是填補無力感的其中一道良方。
音樂有極多種類。古典、交響樂公認良品，但喜歡的人不多，小弟亦不懂得欣賞。搖滾樂有忘憂之能，到今天仍主導音樂發展。外國老舊的情歌，也不錯。聽得太多出自香港的傷心情歌，人只會墮進深淵，而歌曲中總會有一兩句讓我們感到戚戚然。聽得太多 heavy metal、rap、粗口歌會增強我們對社會的控訴性。所以，音樂有好的影響，也有壞。
我們這般八十後，中學時期正是香港樂壇的多產期，多產導致旋律千篇一律，加上粵語歌詞的創作比起普通話困難，作詞人多欠缺文學修養，歌詞總是言不通、語不順。當時，香港樂壇出現不少所謂的偶像派，只有最紅最紫的歌手才會有較優秀的班底，而好的作品更是少得可憐。雖然是少得可憐，但總比沒有好。
人長大後，聽到的音樂廣泛了，聽的不局限於廣東話歌。有時會聽不懂美式英語、聽不明日文歌，但單單是旋律已經讓我忘卻。「世界也許假的，聲音是真的」，說起來很 Matrix、很科幻。在今天的香港，音樂是處方藥物的良伴，深信能夠抗鬱抑躁，但選曲當然要小心，盡可能多元化。

良莠不齊
When I (Chan Sui-jeung, the book writer) interviewed K.M.A. Barnett some forty years after Victory over Japan Day (VJ Day), he was still full of praise and admiration for the soldiers of the East River Column. He was dismissive (輕蔑的) of my remarks about "the Communist guerrillas" by saying that these were "the real sons and daughters of Hong Kong who took up arms to defend their homes. Their courage and sacrifice were admirable. The Communists only provided leadership and organization skill". According to him, there were two lots of Chinese soldiers operating near the border. The KMT (國民黨) occupied the area from Man Kam To (文錦渡) to the west and in his opinion did not do any fighting during the war. After VJ Day, they were mostly interested in looting (搶劫). The other group was the Hong Kong and Kowloon Independent Brigade of the East River Column. Despite their Communist ideology, this group co-operated with the British officials courteously (有禮貌地)and reasonably...
...Barnett was deeply impressed by the discipline and conduct of the East River guerrillas who were occupying Shataukok. Despite their strong national and patriotic feelings, the guerrillas co-operated fully with the British military forces...
...While the main body of the Hong Kong and Kowloon Independent Brigade of the East River Column left the territory and moved north of the border in September 1945, there were isolated pockets that were not eager to depart and were hiding in places such as hills near Shataukok, Lantau Island and urban Kowloon, until 8 November 1945. There were also other people who claimed to be soldiers of the brigade who demanded protection money from shops and cinemas in urban Hong Kong and Kowloon. The military government could not verify their claims and credentials (憑據)...One senior cadre of the column's headquarters told me that he was not all surprised that there were unsavory (討厭的) types among them, as there were six detachments and the headquarters had little control over them. Indeed, the detachments had not always been careful when recruiting their soldiers during the war.

N95 fit test
許樹昌於 HK01 專訪說，N95口罩則較適合預防如肺癆等經空氣傳播的傳染病，也較適合醫護人員等專業人士佩戴，「因為N95口罩封到咁密，呼出嘅二氧化碳呼唔晒，會吸返自己嘅二氧化碳，當血嘅二氧化碳含量高，個頭就會痛。」
