At work we somehow landed on the topic of how many holes a human has, which then evolved into a heated discussion on the classic question of how many holes does a straw have.

I think it’s two, but some people are convinced that it’s one, which I just don’t understand. What are your thoughts?

    A straw is geometrically the same as a circular piece of paper with a z depth of zero and a hole in the middle. Because the z depth is zero there is only one hole. As you add thickness the one hole remains. Therefore, a straw has one hole.

          I counted the ears as 1 hole and the rest as another. Like If I put food in my ear it wont come out through the mouth or urethra.

          Edit: I was wrong, the ears are indeed conected to the nasopharynx and I didn’t know that.
