Hello water is the most abundant ingredient in the human body. With just 15% of the water lost, lives are at risk. Nothing plays a more important role in the food we eat through our mouths than water.

In the predicament of being isolated and helpless, as long as there is water, life will be maintained for a long time; If you can't eat when you're sick, you need to drink water first.
