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?
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.
ears? tell me this story...
You have to rip through a membrane unless you've had tubes implanted for the ears I think?
Yes I google it and discovered my mistake
I'm a weirdo who learned how to 'click' their ears (opening eustachian tubes on demand) on their own possibly before Google existed, and have done a little research between now and then :p
