Eight cups of water / Solution for heathy life

Eight cups of water

The body is about 60% water, give or take. We are constantly losing water from our body, primarily via urine and sweat. To prevent dehydration, we need to drink adequate amounts of water. Health authorities commonly recommend eight glasses, which equals about 2 liters, or half a gallon.
Sometimes we don't know how much water we drink.
In a visual way, showing it on the cup by light will make it easier to control it.
