“I’ll close with this video which summarizes my points.” (No! Never end with a video. End with you!) “So that concludes my argument, now are there any questions?” (Or, how to preempt your own applause.) “I’m sorry I haven’t had time to discuss some of the major issues here, but hopefully this has at least given you a flavor of the topic.” (Don’t apologize! Plan more carefully! Your job was to give the best talk you could in the time available.)
