Why are people so picky about what they eat? Because they don't even think about how they should be thankful for their food because some people are out there in the world and don't even get to eat unless it's dirt. Before you say that you are not going to eat something, think about all the people who wish they could eat what you are eating. Some people are dying from starvation.
Have a heart people.

fluid balance is an aspect of the homeostasis of organisms in which the amount of water in the organism needs to be controlled, via osmoregulation and behavior, such that the concentrations of electrolytes (salts in solution) in the various body fluids are kept within healthy ranges. the core principle of fluid balance is that the amount of water lost from the body must equal the amount of water taken in.
