Being notorious is ironic.

Grandma
Nana, nanana, nana
I miss you, miss you so bad
I don't forget you, oh it's so sad
I hope you can hear me, I remember it clearly
I miss you, miss you so bad
I don't forget you, oh it's so sad
I hope you can hear me, I remember it clearly
The day you slipped away
Was the day I found it won't be the same
Was the day I found it won't be the same
Nana, nanana, nana
I didn't get around to kiss you, goodbye on the hand
I wish that I could see you again, I know that I can't
I hope you can hear me, 'cause I remember it clearly
I didn't get around to kiss you, goodbye on the hand
I wish that I could see you again, I know that I can't
I hope you can hear me, 'cause I remember it clearly
The day you slipped away
Was the day I found it won't be the same
Was the day I found it won't be the same
I've had my wake up, won't you wake up
I keep asking why?
And I can't take it it wasn't fake it
It happened you passed by
I keep asking why?
And I can't take it it wasn't fake it
It happened you passed by
Now you're gone, now you're gone
There you go, there you go
Somewhere I…
There you go, there you go
Somewhere I…
Destination after COVID-19
余光中︰「(我不是教徙)，卻最愛看廟看寺。在京都，我們流連佛寺我古風與禪味。在歐洲，我們仰瞻低徊的也盡是巍峨的教堂……所謂美，倒不一定要怎麼堂皇，像日本京都的禪寺，清靜雅潔，松竹幽深，香火肅穆，也能令人心折。」

數唔係咁計
食物卡路里 (Input) 和運動所消耗的卡路里 (Output) 不需要相等。因為消化都需要能量，譬如身體要製造酵素 (Enzyme)，又例如腸臟蠕動 (Peristalsis) 、逆向 Osmosis 能量少不免。另一方面，不是得到多少血糖 (Blood Glucose)，經 Interstitial (細胞外) Fluid 再到細胞內就可以百分百用上，轉變成 ATP 的過程中一定有 Energy Loss. 打個比喻，一輛汽車入了電油，一定不會百分百轉化為動能，引擎肯定會有熱能消耗。
跟據一個台灣網站，一個六十公斤的成年人游泳四十五分鐘，只能消耗 270 卡路里。而一平碗白飯，大約有 220 卡路里。一個晚餐的餸菜，卡路里肯定多一個開。單看數字已經極不合理。
延伸閱讀︰
Calorie (大楷英文C) 的英文縮寫是 Cal, calorie (小楷英文c) 的英文縮寫是 cal。兩者的中文譯音都是「卡路里」，意思卻有所不同。Calorie是等於1 千個 calorie，由於1千 (1000) 這個數目可以用英文 kilo (縮寫 k) 來表達，因此1 Calorie 即是1 kcal。
1 Calorie (1 Cal) = 1000 calorie (1000cal) = 1 kilocalorie = 1kcal
1卡路里 = 1千卡
但中文名稱裡，沒有分「大楷卡路里」和「小楷卡路里」，我們一般所講1個卡路里，意思其實是1個 Calorie，即1個千卡。
1 kilocalorie (kcal) = 4.184 kilojoule (kJ)
1卡路里的定義就是將1kg的水升高溫度攝氏1度所需要的能量。

Commercial Christmas
耶誕本應是普天同慶的日子，政治動盪、疫情橫行，親人、朋友相聚一刻的機會亦已扼殺。一直以來，香港的聖誕節都是高度商業化。除了教徒，大家都只會覺得這是一個玩樂的藉口。今年零售業嚴重疲弱，各商家都看重聖誕檔期的本土消費。各大百貨公司人頭湧湧，私人派對禁不了，深深違反了防疫原則。如果變種病毒由酒店轉移到社區，後果不堪設想。
今個聖誕都是在工作中度過，一月中旬會由中華員工變由商務職員。

I'm with you
Isn't anyone trying to find me?
Won't somebody come take me home?
It's a damn cold night
Trying to figure out this life
Won't you take me by the hand?
Take me somewhere new
I don't know who you are
But I... I'm with you
I'm with you

夢與現實
有一個夢重重覆覆，讓醒來的我也記得當中的片段。夢中，我知道自己有大學學位，但仍在中學上課，還時常在考我害怕的中文卷。現實中，香港大學護理學學士對我來說只是虛名，在職場上沒多大作用。在大學時期處理魯莽，有一次得罪醫院高層，很多同學都視我為麻煩製造者，他們覺得我破壞了校譽，集體杯葛我，頓時朋友銳減。言行小心，是付出了很多，才學到。職場上的是是非非，人前人後，雖然還有很多進步空間，但都算中規中矩，不適當的言語都不會出現在不適當的地方。
話說回頭，我曾申請報讀理工大學職業治療，但人家連面試機會都不給予，相信是因為我的中文成績。曾經歷高級程度會考的小弟，考DSE一定不會輸給現在這一輩。不過，我要用二年時間 Full Time 準備，加上讀大學，這個計劃的經費是天文數字。這個夢的出現大概是因為我心有不甘。雖說書店的工作不是甚麼低下的職業，但我志不在此，也不是專長所在。人生，有很多東西想得到，但需要有很大的決心，還有許多客觀條件箝制。不上班去上學，孤注一擲，職業治療師的執照也不是可以輕易考取。安於現狀，其實也是一個選擇。

自私卻迫於無奈
外傭休假如果不留在雇主家中，可以到哪裡？她們離鄉背井，公眾假期與同鄉聚會本是人權，但是武漢肺炎大流行下，人人自危。疫苗不遠了，為何不可忍耐一下？百思不得其解。雇主或其他香港人是否可以做一個榜樣，冬至、耶誕、新年避免聚會呢？難道疫症殺到你住的那棟大廈才懂得驚驚青青？Panic 是不需要，至少要謹慎。
吸煙者煙癮發作，在公眾地方除口罩吞雲吐霧屢見不鮮。但是，可否等到工作後在家才吸煙？我不知道，因為本人不是煙民。可是，他們甘願冒被罰款的風險，煙癮不可看輕。戒煙是否一項易事？戒煙貼、戒煙口香糖是否真的有幫助？但研究指出加熱煙無助戒煙。
【港大研究發現加熱煙無助戒煙】
香港吸煙與健康委員會聯同香港大學學者率先公布本港加熱煙的調查數據，以及首個研究發現加熱煙無助吸煙人士戒煙的結果。
一項由香港大學護理學院副教授王文炳博士帶領進行的研究，於2018至19其間追蹤本港1,012名有意戒煙的吸煙人士六個月，結果發現加熱煙無助戒煙。約四成半（44%）吸煙人士使用加熱煙戒煙，然而六個月後成功戒煙的機會並沒有提高。另一方面，對比沒有使用戒煙服務的吸煙人士，有使用戒煙服務的成功戒煙機會在第六個月提高了七成（70%）。相關研究刊登於國際醫學期刊《煙草控制》。

余光中《讀夜》
「氫 (Hydrogen) 以為體，氦(Helium)以為魄。」
Nuclear fusion (原子核融合)
氫轉氦開始時需要極大能量，融合後核心質量會減少並釋出能量。
(Image: https://www.britannica.com)
Nuclear binding energy 越高代表核心越穩定，意味分拆該核心要很大能量。

Rt tends to 1
Effective reproduction number at time (Rt) is the average number of secondary cases per one case at any given time. This number will vary as the outbreak progresses, and indicates real-time transmissibility. Effective control measures and behavioral changes, such as quarantine (檢疫隔離) enforcement, usage of face masks, travel restrictions, class suspensions, and social distancing, are all factors that may affect the Rt of a virus.
Rt = 1
Each infected patient will go on to infect one other person. Statistically, this would mean that one new infected patient will replace another who had recovered or passed away from the disease. This also suggests that the outbreak is stabilizing, with no changes in number of infected people over time.
something about music
原音樂及原音樂器是在20世紀電子音樂面世後，為了將傳統真實的、未經電子處理（或不是由電子信號產生音波）的樂器與之區別而衍生的返璞詞。英文中分別用了兩個詞來表示，一個是「acoustic」，原意為聲學但在這裡被引申為「由真實樂器天然地產生的（聲音）」；另一個「unplugged」則表示「不經電子處理的（樂器）」。

惡夢
幾天前夢見母親離世，半夜醒來，哭起來。事實上，父母與自己的永別遲早都會發生，這種悲哀一定要經過、經歷。
When I wake up in the middle of a dream, even when I close my eyes again, I can't go back to it. The world that was so clear in previous moment is now a phantom.
I'm running out of energy for this losing battle. If I forgot the days when I burned with love for you, I wouldn't be me. Tell me the right way to say goodbye.
My memories have suddenly seized me roughly and won't let go. I love you, still, deeply. A midsummer shower that won't stop falling.
In the never-ending, never-ending rain.

Definition of Epidemiology
流行病學常與抗擊流行病的意念聯繫得太頻繁和太緊密：epi（上），demo（人）和 logos（要研究），實際上它包含了更廣泛的概念。
流行病學是對人類健康狀況或事件的分佈和決定因素之研究，並將其應用於控制健康問題。 流行病學的核心是使用量化方式研究人群中的疾病和危險因素。
Epidemiology is still too often and too closely associated with the idea of fighting epidemics: epi (upon), demos (the people), and logos (to study), it actually incorporates (納入) much wider concepts.
It is the study of the distribution and determinants of health-related states or events in human populations and the application of this study to the control of health problems. The core of epidemiology is the use of quantitative methods to study disease and risk factors in human populations.
