I wonder if that nurse was confusing "cups" with "ounces".

Or maybe “four to eight” cups. The idea of drinking almost 12 liters of water each day is pretty amusing.

Ha! would love to see that scene where the nurse gets shit from the doctor.

Isn't the 8x8 rule that they try to expand on firmly established to be pseudo scientific myth? https://journals.physiology.org/doi/full/10.1152/ajpregu.003... Woo + math == woo

I think the 64oz assumes you will get more from food and other beverages besides "water" and is probably plenty for an average person with an average level of activity.

As we age our "thirst response" becomes less reliable. I really don't get thirsty until I am starting to become dehydrated. It's good to have a guideline to inform my self-imposed daily drinking regimen.(which I have a hard time keeping)

It is probably best to follow real information then. Note that while your thirst response may be declining as you age, mine hasn't. Annicdodes aren't data, mine or yours. IMHO the 8x8 myth may or may not be optimal guidelines for you as they aren't based on anything but rumors.

> Several studies have demonstrated that elderly persons have lower total water intakes than younger adults, and that women are particularly at risk of too low an intake.

Yes. There is no medical basis for any amount of water above "what you're thirsty for".

Our thirst system is as precise and robust regarding water as our pancreas is for glucose.

Given how critical this is I suspect your body is better at it then you are... I'd say "Drink when you are thirsty".

And when your pee is yellow / yellowish ...

I'm pretty sure yellow pee is normal. It's when it gets dark and turns towards brown that you have a problem.

My pancreas doesn't tell me when I need more sugar.

Y'all took me quite literally as I exaggerated for effect. I am merely a panel in that xkcd comic. Which hat I am wearing is left as an exercise for the reader.
