I was just wondering why we pucker when we drink something sour.
Am I correct in thinking it's to use our lips to protect our teeth from the
acids that make the sour taste?

COMMENT:
Nobody knows, but note that the puckering action also is what you use
to work up saliva. Since sour things also are great for increasing
saliva production, I presume both actions have to do with trying to
*dilute* the acid.

It's tough to reason this on a teleological basis. It may in fact have
been protective at one time, but I can't see any real adaptive value for
the world we live in today.

People pucker and salivate when they taste something unpleasantly
bitter or astringent, too. Generating more saliva makes it easier
to spit all of a noxious substance out.

Another thing to consider: Try swallowing while you're puckering. Not
very easy. Perhaps it's a reflex that prevents swallowing.
Now can anyone figure out why it's impossible to sneeze with your eyes
open? I'm stumped on this one.

Not impossible, but very hard. Perhaps nature is trying to protect you
from a poke in the eye while engaged in rapid reflexive head motion.

Are you able to keep your eyes open while sneezing? I've tried to do
it, but I can't.

These are my opinions only, but they're almost always correct.

I've always assumed it evolved as a protective reflex -- sneezing can
kick up dust, which you don't want in your eyes.
