"And feces contains among other things destroyed red blood cells." So...you are comparing urine, which is basically a filtrate of blood and a sterile fluid, not a solid, not something that contains disgested & undigested food particles, not something that travels through the intestines - to a no way sterile, solid, bowel movement?

I'm sorry but that is where a valid comparison no way lies.

It is as valid of a comparison as comparing urine to blood, which was my point. Urine contains dissolved solids and sometimes even solids. And it is not always sterile. So your ignoring the similarities is just proving how far you are willing to go to avoid the facts. And this includes the fact that urinary pH DOES NOT reflect blood pH. They may be related just like feces and blood are also related but this does not make them the same thing!!!
