Nuthin there that anybody can argue with. Seems to jibe with my experience.

Though I think amount of chewing is a big variable, swallowing big chunks means longer in stomach to dissolve.

Without data on how many beers are drunk, and how fast, there is no way to answer.

Temperature of food/fluids taken in, level of acid production, mass of food taken/time for that mass to be taken in, brain receptors receipt of and response to signals both for fill level and level of various processes over time. And, of course, the makeup of the foods. Averages are what it looks like (and makes sense). What you need is a textbook on physiology for CSI type offices/coroners.


Before it gets into potential woo, this is a pretty good description for a normal meal: http://www.ayushveda.com/diet/physio...on-stomach.htm
