While you can pause mid story, you don't want to trail off mid-sentence because it makes you sound like you don't really respect whatever you're talking about.
Some of those sound quite nasty. Fainting is when you lose consciousness and pass out; and your gullet is the tube through which food passes from the mouth to the stomach, so a burst gullet would be horrible.
Cyclists, in particular, might be thirsty at this point, and you can get a drink from the soda fountain to the north of the bike park, halfway to the museum entrance.
