Can we settle this: how many holes does a straw have?
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?

This seems overly reductionist to the point where I could just as easily describe my mouth and my anus as the same hole.
Yeah, that's a concept that gets covered extensively in anatomy, immunology, and microbiology. It's called "the donut model". This is not a joke. It clearly shows how your digestive system is exposed to the outside world, similar to skin. You can obviously see why this is important immunologically, since germs can just get into the mouth/butthole in a way that they can't penetrate skin.
It's one long hole.
that is actually the case. there is an unimpeded path from your mouth to your anus
Because they are the same hole. Welcome to topology
It's perfectly reductionist. You have defined our biology in exactly the same way medical texts do.
Now you're getting it!
Yes. It's called the gastrointestinal tract.
