i don't think i've ever directly appreciated the mouth's ability to suck liquid up from a flat liquid surface (like sipping tea or idk drinking face down from a lake if you ever had to do that)

Bodies are amazing! Typing 200wpm, throwing a baseball 100moh, riding a bike 200+Miles a day, surviving in extreme conditions like Everest, deserts, rainforests, outliers of every kind good and bad

Worth noting that most animals cannot in fact do this (no cheeks), and so have to rely on lapping and such

And from a cosmic frame, we can't, really: we just create a "partial vacuum", and then rely on the weight of the atmosphere, caused by the gravity of the earth, to push the liquid up into our mouths. That we can articulate our lips well enough to create a suitable seal.

TIL: Until recently, the muscles around the mouth were believed to be a sphincter muscle, hah.
