Today, I attended a ten minute presentation which made me so impatient that I had to restrain myself. As I was a guest, I felt that it was improper that my eyes (investigative), the expression on my face (disgruntled) and my body language (tense) gave away my feelings. I needed to relax fast and attain the same blank pose as the other members of the audience. Accordingly, I decided to start counting backwards from 200.
Hereby, I define the ”200 TEST” for public speakers: if your presentations make people count backwards from 200, you should perhaps do something about them.
