The language of the speech is straight-forward (subject-verb-object), as requested by the communication means chosen (oral). Short sentences, simple structures and common language are privileged. Since the ideal audience of the video is a heterogeneous group of people with different knowledge backgrounds, only a few basic terms of specific language are introduced to the listener, in order to make the topic accessible to a larger audience.

The first few sentences of the speech have an introductory function. The argumentation starts with two statements each followed its own justification. The second sentence is introduces by the conjunction “and”, as it provides additional information. The statement-justification structure is highlighted by the two colons, that have an explanatory function. The last sentence contains the declaration of intents of the speaker. It recalls the structure as the previous ones, with a first statement (that also contains an apology in case of failure of the experiment) and an explanation, divided by a colon.

The false start “So, here we go!” concludes the introduction and starts the body of the argumentation.

The following paragraphs provide the description of the items the speaker is going to use to show and interpreter the data, their function and the way they interact with each other to create meaning. They are organized like step-by-step directions, with the use specific language and the definition of clear reference figures. The following sentence begins with the conjunction “so” and provides a less scientific and more practice explanation to the Cartesian graph.

The following two sentences provide a visual legenda  to correctly read the data thanks to two simple parameters: the colour and the size of the bubbles. The two sentences are linked by the conjunction “and”.

After that, the speaker describes the situation of the world in 1810 (the start point of his observation) according to the two indicators represented by the axes (health and wealth). He uses a very informal language and tries to involve the watcher in the analysis with questions.

Another false start (“And now, I start the world!”) introduces the real start of the experiment.

The following paragraphs  introduce and describe the results of the main events that represented turning points as regarding health, wealth and the countries’ relations according to these indicators. The main steps highlighted by the speaker are:

- the industrial revolution: European countries move away from the rest, while Asian and African countries stay poor and sick
- the First World War and the Spanish flu epidemic: impact on life expectancy
- the Great Depression: western countries go on towards greater health and wealth
- 1948: considered as the most important turning point. This is the point when the differences between the rich and poor countries were wider than ever, but also the beginning of a new world trend
- up to 1970s: rise of the former colonies as the new emerging economies
- today

Every point is dealt with a rapid series of statements summarily depicting the situation. The terms “health” and “wealth” are used very frequently, to focus the listener’s attention on the two core indicators thanks to repetition and assonance. For the same reason, countries’ names are repeated over and over again and their mutual situation is conveyed towards a list of rapid subject-verb forms divided by semicolons. The rhythm of the description is pressing, as could be seen thanks to the great number of short punctuation signs (commas and semicolons). The passages between two different point is marked by the expressions “and now” or “here we go”.

The speech gains again a slower rhythm as it comes to analyze today’s world situation in detail. The colon signifies the intention of the speaker to explain the concepts further and better. The conjunction “but” introduces an addition information that slightly contradicts or resizes the previous statement.

The following paragraphs summarize the considerations drawn during the whole exposition. The speaker draws his conclusions on the base of the data he has analyzed. Again, he resorts to assonances to focus the listener’s attention on what he’s saying (West-Rest, aid-trade, healthy-wealthy).

In the very end of the speech, the speaker explains what is there behind the video the watcher has just seen, quoting the approximate number of countries, history years and data involved in his presentation. The aim of this is to make the watcher understand that is possible to transform such an huge amount of plain data into something understandable and even enjoyable and, therefore, that he has succeeded in his initial intents.
