Yes, the science has moved to "drink when you're thirsty" a long time ago and it's annoying how many people believe drinking 3 liters of water per day is a key tenant of human health.

All that being said, I'm not sure GP was necessarily endorsing the idea that you should drink a certain amount of water a day. I read it as a suggestion to pull away from the screen and listen to your body

Some folks' interrupts are buggy, so they resort to polling.
