When you hear “unboiled” water, you may think of germs or uncleanness. However, this “unboiled” water is the natural water, and best for our body.
People used to drink the water which directly wells up from the earth. At some point of the history, however, they started to say that do not drink water directly from the well but to boil well once. It may have started when the industrial chemicals were used by humans in the natural world.
Since then, unboiled water became the enemy of a good health. As a result, our bodies have run out of minerals which we could take in from the spring water or plants without special consciousness.
Even so, there are still places where you can enjoy spring water. Moreover, some use the water for tap water without boiling it.
I really think those people who can drink spring water as if it were air are very lucky.
