summary

The composition of saliva is very complex, in addition to a lot of water, there are a variety of bacteria, lysozyme, and some protein molecules produced by human body. After saliva stays on the surface of water cup or skin for a period of time, the water gradually evaporates, and the dark and anoxic environment also changes.
