I am grateful for water.
It is more than half of what I physically am. An amazingly simple molecule composed of two hydrogen atoms bonded to a single oxygen but absolutely essential to life.
It is easy to take water for granted. I live in a land of abundant fresh water. I don't have to walk a great distance to find a clean water source. My ancestors would be amazed that I have several places in my home where I can conjure both cold and hot clean water with a simple flick of the wrist.
Is there any substance more important than water?
