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?
Almost. First you need to choose the minimum size of a hole. If you define a hole as something just a bit larger than skin pores, a human has 7 holes. Even when defining a hole as something around 1cm, you have at least 3 holes (your nostrils, mouth and anus share one cavity).
