I have read that if you fold a piece of paper 103 times
that its thickness will exceed the size of the known universe,
93 billion light years.

So, assuming great care is taken – precision folds, impeccable creases, etc –
one should theoretically be able to use a single sheet of toilet paper
to wipe their ass for an entire lifetime.
