…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.


Honestly I’m an extremely sweaty guy and let me tell you electrolytes will change your life. After doing yardwork I’d feel almost hungover the next day. Started drinking just one electrolyte type mix with my normal torrent of water made a night and day difference.
Thanks. I’m always tired too, maybe some elecs might do something.
