So, when you chug water during your meal, the stomach "knows" to pass that on faster, even though it's now mixing with the chyme and potentially creating a diluted concoction?

It makes sense that liquids are processed faster, it must just have to do with receptors in the stomach recognizing that there is water present and to just let it pass, for lack of a better analogy.

Fit a square peg into a round hole. Interesting, I wonder if the stomach just only allows the chyme to pass, and everything else just keeps mixing until it's broken into chyme

That makes sense, I just don't understand how the stomach knows when it's acceptable to pass food on, and how, if other food enters at the same time.

I think it's more like; at some point, life becomes too difficult to have birthdays - forget about the cake

Not if you take the bullets out of the dead guy and re-used them
