There are two ways of losing an audience: going too fast is by far the rarer of the two. Going too slowly is actually the bigger problem, since it allows time for people’s minds to wander off. I feel a bit guilty saying this, but if you speak quickly enough, you can get away with the odd leaping segue. I don’t recommend blatant non sequiturs, obviously. Speaking fast also papers over a lot of cracks—no one minds or even notices the odd um or er provided they come quick and fast.
