Without water, we will die. Therefore, water is the lifeblood of all humans on this Earth. Water is used in food, drink, without it there would be no fruit, crops, seafood, Capri-Sun and much much more. It tastes good, yet has no taste. It looks good, yet has no ego. It refreshes and quenches our thirst.
And it has exactly zero calories.
Pretty damn amazing that something so important to the survival of life on Earth and food in my stomach is, in reality, one very big ZERO.
