Fellow speaker,
Some things you can control as a speaker, some you can not control. Professional speaker Jim Stoval says, "Control what you can, acknowledge what you cannot." For those times you can't control something in your presentation, acknowledge it and move on. For example, if it is too hot in the room, acknowledge it with something like, "I know that it is a little hot in here. Maintenance has been called and will be solving the problem soon."
Moving on,
