The summons from a medical congress or symposium chairman, chairwoman or president to be a session moderator or to deliver an invited lecture, or the offer to participate in a free paper session are events which can turn the most seasoned clinician and researcher into something which lies on the bed of the ocean and shivers, namely, a nervous wreck. However, proper planning and the following of a few simple rules can eliminate the mental trauma for the presenter often wrongly associated with having to give an oral presentation, and indeed obviate the sometimes much more serious trauma inflicted upon the hapless audience by an ill-prepared presentation and a hapless presenter, not to mention a mutinous moderator. The first point is that an oral presentation is not a scientific paper, and therefore while it may follow in general the usual divisions of a written article, it should not be a pictorial representation of a piece of rigid scientific writing. Secondly, presenters are almost always given a time limit for their presentation. It is the height of bad manners and total ignorance to exceed this time limit, as the presenter is often one of a series.
