Now, I have some reservations about turning everyone into stand up comedians, but I did like that last line about “I will never resort to PowerPoint in a lecture again”. It is important to interact with the audience, and I think we do often hide behind our visual aids. Anyway I’m always open to learning from strange new sources. But I’ll stop blethering on, and let you read and judge for yourselves.
