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?
Are we considering it 3D then? I thought we’d be thinking of it as a 2D surface (which, for the record, has got 2 holes).
