Working the night shift is no good, I know. You don't need me to tell you that. Unfortunately, all-nighters are part of life for many of us.

The struggle with sleep-anaemic mode of work is constantly playing havoc with our internal clock. Worse, should you read the neuroscientist Mathew Walker's book Why We Sleep , you will hear the bad news: the shorter your sleep, the shorter your life span.

One inside story of the book is how birds' sleep pattern

"Here's a question," my wife quizzed me last weekend. "Do you know what day is it next Sunday?"

"Yes, I think it must be an important day," I nodded.

When I realized I was caught red-handed without much idea, I averted my eyes from my wife, the way a medical student stares down at his feet like he can find the answer to a professor's question written on his shoes.

I waited. I waited. I didn'

At a recent final year medical student examination I was glad to have the chance sitting next to Professor Sung, our truly legendary physician. Like a student myself, I'm always hungry to hear his stories, which are at the very heart of Dickensian or Sherlockian flavor.

A lesson I learned was how we could have behaved like an asshole or bosshole without knowing it. The unfriendly and rude bullying behaviour of senior doctors was much more common in the old days, as I was told, when superiors treated young followers

The world has become so small so quickly. A virus surfaced four months ago, and swiftly sweeps across the globe. This seems so sudden.

One of the social upheavals arises from city lock down, closing school, and isolating one from each other. Here's a heartbreaking reality: people can't visit their parents, even on their deathbeds, for fear of spreading the virus.

In these crazy times, we all need some encouragement to keep ourselves calm. To choose joy for the family, my wife

If you find yourself being addicted to the screen and social networking, be warned that the screen activity is now measurable and easily tracked in real time. Your device simply tracks your average time spent daily on WhatsApp, Instagram, Facebook and answering mails. There's no best way, but remember that statistics aren't too useful to stop us from dawdling in front of the screen.

Let's be candid with ourselves. Instead of bemoaning the lack of high-tech productivity tools, we should begin with simple

Humans are profoundly social animals, and our relational connections shape our inner neural connections. Much of the time, we need more than reasoning to maintain social distancing even if an infectious disease outbreak mandates it.

And that's no small thing. Social distancing is never easy. And it's even more difficult for kids. Dr. Ainsworth's groundbreaking "Infant Strange Situation" study discovered attachment science, and changed how we understand the importance of secure attachment or intimate human relationships for kids.

Here it is in

Recently, weighed down by the ever-present concern about epidemic of coronavirus infection, doctors are often separated from patients by double doors. Even when doctors muster the energy to go through the doors, the patients should still be examined with gloved hands.

That's what I have been - and supposed to be - doing in the medical wards catered for patients returning from Wuhan province or Korea.

Eager to get an accurate diagnosis, we are instead relying on advanced imaging techniques or laboratory tests like real-time polymerase-

The problem with long working hours in hospital is not that we get overloaded. The problem is that we have had almost no idea how to call it a day.

We've decided that there should not be long shift for doctors looking after quarantined or suspected coronavirus patients in our hospital. If safety and protection are what we sought in such high-risk areas, we should limit the hours of physical and mental stress from putting on and off the full personal protective equipment, as well as mindful hand washing.

I remember the story of "9-enders" (aged twenty-nine, thirty-nine, fifty-nine) who are much more enthusiastic to run their first marathon. In many ways, the left-digit bias reinforces our tendency to categorize continuous variables on the basis of the left-most numeric digit.

The susceptibility of our brains to fall into the trap of heuristics or hard-wired mental shortcuts is common. It can affect many of us. And we (and by we I mean runners,

First, a disclaimer. After reading this blog, you don't have to follow my type of "workouts."

Entertaining the thought of prescribing the same training intensity for runners, as I have recently learned from reading Hansons First Marathon , is the surefire way to let old injury rear its ugly head. Overzealous goal means taking two steps back for every step forward.

Yes. I asked myself question to get a clearer handle on my natural abilities. That's going to differ for individual. Let me say
