…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.
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 :)
