…because the shape of the water bottle isn’t uniform either. Part of my new year’s resolution is to drink 4 liters of water per day, so I spend a lot of time looking at those lines. Edit: 4 liters is a lot, but appropriate for my size and activity level. Without conscious consideration I don’t drink enough water. It looks blue because the bottle is blue.


I don’t think this is completely true. Caffeine may cause you to empty your bladder, but your body continues to function normally, and will keep blood concentration of electrolytes at homeostasis.
Compare this to alcohol which removes water from the bloodstream, which increases concentration of solutes in the blood.
That’s fair. I’d be curious to know more, but don’t know enough to argue it. I’ll let you know if I get around to investigating further haha
Anyway, I want to thank you for an intriguing and entertaining conversation. It’s nice having a good long discussion with someone with diverging viewpoints. All the best in this new year :)
