Young people enjoy different kinds of drinks, though they know drinks are bad for their health. What about you? What will happen to you if you only drink water?

Chris Bailey, a popular blogger (博客作者), tried this out. Here is what he has found.

First, you lose weight (体重) faster. Yeah, you do! You don’t have to exercise but just keep away from drinks for 9 days. It is the same as running for 8 kilometers a day! So write down your resolution (决心) on a piece of paper and put it on the wall. And you will see the result soon.

Sometimes when you have to stay up late for a test, a cup of tea or coffee is usually put at the side of your desk. But do you know 75 to 85 percent of your brain (大脑) is water? Nothing else! Just by drinking water, your brain can work efficiently (有效地). You may remember things quickly and well.

What’s more, water washes out something bad in your body. So drinking enough water can stop you from getting old quickly. If you want to look young and beautiful as long as possible, drink a glass of water right now! Keep on doing it for longer, and you will be surprised to touch your soft and clean skin (皮肤).

Lastly, you save money! How much money do coffee and juice cost you every week? The price of water is much lower than that of other drinks. Drink 5 glasses of water every day or visit doctors? Think about it!

So, what are you waiting for?
