I have a phobia of saliva- it grosses me out!
I agree with you!  Saliva is a watery substance formed in the mouth and saliva glands
Ugh I hate seeing someone spit! It's disgusting. 
Yeah i agree, another fact is human saliva comprises 98 percent water very strange
Even though I know it's essentially water, I still find it yucky. Do you?
Yeah its very gross, it also contains mucus , white  blood cells, and epithelial cells
Oh. Well maybe that's why it's so disgusting, it's full of body stuff!
Another very gross fact is its the beginning the process of digestion of dietary starches
Ewwww you mean it contains enzymes to break down food? Yuck!
Yeah thats what i mean !  It contains actual starches and fats
