The speech of Ron Gutman on smiling is the example of an effective presentation. At first, the scope of information seems a little confusing as the speaker starts presenting different facts at a fast pace. However, even though most data were received from various studies, he successfully integrated them into one story. The reflection on human superpowers followed by the effects of smiling on marriage and wellbeing lead to the conclusion that it brings many benefits for health and happiness (Gutman, 2011). Another peculiarity of the speech is the fact that the speaker does not get distracted when switching through the slides. He does not look at the screen, and it adds credibility to the information. Meanwhile, the possible improvement of this presentation is the inclusion of personal experience.
