Used water

You may drink water that maybe previously drank by a dinosaur .... maybe a few drops of this glass have been given to you before a beast ... It is also possible to think that some of the water available in the glass has some part of the massacre or all the time long before the body of a great human being ... I do not believe or drink your water. It is not a fermented butterfly water. Your glass may contain ocean rivers across the world, canals and watermelon water or no amount of water.
The water that you are drinking or drinking is the same water all the time before it is thirsty. It will also be consumed several times after your drinking.
Do not worry ... read science ... knowing water cycle can solve your conflicts.
This is all the work of water cycle, since the world has come into existence, with the help of clouds and flavors, it is rotating around the whole world.
