Language was designed so we could communicate internal feelings and experiences to one another. Just compare peoples descriptions of getting kicked in the nuts and delivering a child, and you will easily be able to tell which is worse.
We can make comparisons even better than that by talking about something that everybody can experience: passing a kidney stone.
Now I've heard this from many women that they'd rather give birth than pass another kidney stone. And I've heard from many men that passing a kidney stone was about the most painful and miserable experience of their lives. So if everybody could sort of rank their pains on a scale, we could make direct comparisons and determine what is more painful. a kick to the nuts or giving birth.
