The four rooms of the heart
Two small rooms on top, two big ones below, and the doors between them.
The heart as a kopitiam
Orders come in, orders go out, and the stall never closes.
A talk at the void deck, with questions
What people asked last Thursday, and how I answered each one.
Why your pulse changes on a walk
What the beat is doing when you climb a slope, and what it is doing at rest.
The two numbers on a blood pressure reading
What the top number and the bottom number each stand for.
Why I write this letter
From a hospital ward to a whiteboard in a community hall.
The letter
A letter every Sunday
One idea about how the heart works, in words you can read over coffee, and the dates of my next talks. Free, and short.
