My darling mother,

It must be about six months now since you last heard from me, but now that I am home again in dear Old England you will hear more often. I am in this hospital for recouperation, as I was so run down with disentry through bad usage while in German hands, and not only that, we have been on a long march over a thousand kilometres, starting on January 23rd and being recaptured on the 12 April by the 9th American Army at Brunswick, but I had already been admitted into hospital on the 11th.

Principles of Calm Technology

Require the least amount of cognitive overhead

A tea kettle can be set and forgotten, until it sings. It does not draw constant attention to itself until necessary. A tea kettle's whistle brings information from another room to one's attention.
Provide information without distraction

An inner office window provides an understanding of whether someone is busy or not without the need to interrupt them.

Task 1

Read the snippet of code below. Can you explain what is going on? How would you use this code to get the person's age?

// A person 'object'
var person = {};

// The person's date of birth (a date 'object')
person.dob = new Date("September 15, 1984");
