It would be so much easier if I could just randomly speak thoughts aloud and have them recorded. So many things running through my head & I get a lot of ideas when I'm driving, but can't write 'em down. Very inconvenient.
I wonder if other species' tongues are also just for taste or for other purposes? Like, frogs use theirs to catch prey, right? And snakes use theirs to pick up scents so they know whether a prey or potential mate is nearby.
Also, how do we know tissue is clean? We take for granted that it is, but what guarantee do we have, really?
