The Instinctive Drowning Response

It seems weird that your body wouldn't be like, Oh yeah, let's get the legs in on this too. And maybe that'll actually help keep us above water. I wonder also if it's because as you're getting a lower concentration of oxygen and you're becoming a little more sluggish, kicking your legs is actually harder than flapping your arms. You can still be vertical in water and like, you know, treading water and kicking. Yeah. Maybe someone can fill us in on that one.
