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.

    so, using this logic, how many holes does a human have? 2? 2 1/2?

    1. Two ears, two eyes, two nostrils, one mouth, all connected to the anus.

    You have to rip through a membrane unless you've had tubes implanted for the ears I think?
