After 30 or 40 years, the stomach slows down

It's long been noted that grandpas and grandmas have considerably more indigestion than younger folks, but their indigestion generally has been ascribed to "being older." Not much thought has been given to the possibility that the "being older" could (at least in part) be due to the indigestion!
Let's give it a little thought. If we have bodies made up of some 60 or so essential nutrients (essential being defined as nutrients without which we sooner or later would drop dead), then how healthy are we going to be if even one of those essential nutrients isn't getting through very well?

After 30, 40 or more years of digesting or attempting to digest everything we put in our stomachs - not just food, which the stomach is designed to handle, but also refined sugar, caffeine, distilled alcohol, grease and oxidized oils, fluoride and chlorine from water, chemical flavorings and colorings, pesticides, herbicides - you get the idea, no? - why would anyone except an antacid salesman or the average gastroenterologist imagine that our stomachs would make more acid, more pepsin, and digest things more efficiently as we get older? Common sense says that after 30 or 40 years, the stomach slows down, just like the rest of us, and makes less acid, less pepsin, and digests things less efficiently.
