Unidirectional air flow, whats the big d… oh.
Imagine your blood flow was not unidirectional. Not arteries and veins, just… vessels for both directions. You’d like – have to pump blood down into your extremities one heartbeat, and with the next one draw it back towards the heart. With the added malus that you only get partial replacement of blood, because you cant completely constrict your vessels.
You probably couldnt even leave your bed, let alone stand on two legs that way.
Right? Birds got it going on. Meanwhile, we’re sitting here like, “Whew, I’m gonna need a breather after taking that last breath”
“Whew, I’m gonna need a breather after taking that last breath”
This is absolute poetry. FFS, our bodies are such absolute half-baked hack-jobs that we can’t even honk properly.
Conclusive proof all species of geese are assholes
Superior assholes
And lungs.
