completely acceptable,extremely polite-and totally predictable
typical opening remarks that most speakers make are benign and boring
signal to the audience that what they are about to hear is nothing new,or innovative,
or even interesting
even if you're getting ready to share the most incredible news in modern medicine,you have already lulled your audience into complacency
capturing your audience's attention the moment you begin to speak and then keeping their attention throughout
A good opening also establishes your believability and credibility
