Water, drink it. Seriously.

I've just read something interesting in a magazine.
17400 Calories is what you would burn per year if you did drank 6 cup of cold water. German researchers says it's the body trying to warm the cold water intake that makes the body burn calories.

...Go, eat ice cream! Very cold ice cream!!.... ok... that was my sarcastic moment.... lol

Seriously, that would just be another good reason to drink your water, so do it! DO IT!

Don't lik water? Bad reason, add a lemon, a cucumber, a piece of watermelon!
