"You should drink plenty of water. You have to drink eight glasses or two liters of water every day.
We all get such unsolicited advice. But that's not always the case with water.
Until the early 19th century, drinking too much water was considered bad. The upper classes of society considered it an insult to drink too much water. They thought that it was the job of the poor to fill their stomachs with water. They considered it against their dignity to do so.

"If you listen to your body, it tells you when you're thirsty," said Courtney Caps, a British doctor and athletes' health adviser. People are wrong to think that getting thirsty means that it is too late to drink water. Man has been quenching his thirst for such symptoms for thousands of years.
