In order to count anything, you have to apply some kind of equivalence relation to the world to decide which things belong to the category of things you’re counting—so there’s some degree of subjectivity involved, and you’ll most likely divide the world up into things whose quantities are manageable. If you’re counting the number of times something happens, and the number gets too big to keep track of, you need to be more selective about what qualifies as a countable event. And it’s been established that the point at which numbers get unwieldy is around 42.
