Ever since I was a child, my mother told me not to spend so much time in the shower... "Get out of the shower! now!", my mom said.
But, do we really spend that water? what happens to those H2O molecules? do they dissapear? do they become useless anymore? or do they simply go to another part of the finite vase that we have and they will return someday?
