you see, i GET what MH is talking about. and i can easily see how this can be missed. i dont have the wherewithall to just had it to you the way i get it. i agree with what you say. i can see that too. in fact, i believe the whole reason adults still have the ability to produce hcl is what you just stated - in case we ingest pathogens, or meat, or whatever. but going beyond that, all of those things are a choice. in this world, created entirely out of light, free will is king and faith is the queen that rules the roost.
