“A human being can live without food for several weeks because the body uses its fat and protein stores to help it in this process. A fat person is likely to survive for a longer time than a thin man because of the quantity of fat stores. Yet a lot depends on the person and it is certain to leave a person with a lot of tiredness and lack of energy. But water is an entirely different case. A person would most certainly die if he has to go without water for three or four days at a stretch. The size of the person is of no consequence in a situation when there is no water. Thus it has to be concluded that water is more important than food as lack of water leads to dehydration and ultimate death. The water content in the body has to be regularly maintained.”

Of course, to flush the toilets we keep a large container nearby to pour down the toilet rather than use up the filtered water. We use the unfiltered water for this task.
