Why are hair straws so repellent to swallow?
Why is it that hair straws are really not what you want to have in your mouth, or worse even, swallow:
They don’t make any harm or pose any physical threat to your body, so how can it be that one reacts so repellent to a single tiny straw exhibited in ones mouth, when there are other lifeforms out there, willing to swallow large balls of hair?
