I drink coffee, which is made mostly from water. I seldom, if ever, drink the pure stuff. That fact can drive healthy people nuts. Oh well. Some things never change.
Water is incredible stuff. Unlike us humans, the mass amount never varies. It is able to magically change into three distinct forms, while we continually come and go, but the finite amount of water molecules present on planet Earth is unchanging.
Here is a creepy thought; whatever bit I have consumed over my lifespan has been recycled more times than I would like to imagine, and most likely, was drank by others before I arrived.
Yech, you say? Well, some things just never change.
