Awful.

The cafe looks distinctly... grim. The walls are some kind of rough clapboard, and the flatware has become some kind of crude, wrought-iron looking stuff. The whole place suddenly has a distinctly Amish feel, albiet without the nonviolence and sense of humour you associate with the actual Amish. You look around the cafe, and notice that there are no women around any more - just a couple of dour-faced men with long beards. The place feels like a bad biker bar, only with worse music.

Right - that kind of makes sense actually. Cultures that sequestered their women must have outcompeted more liberal ones, and this... You think on what you know of recent history, shuddering at everything that's gone on. You quickly erase the rule you just made, sighing with relief as the world shifts around you again...

You realise that you can barely remember the world your single rule change had created - that won't do. Under 'Metaphysics' you write:

NEW RULE: THE OWNER OF THE RULEBOOK RETAINS MEMORIES OF THE WORLD BEFORE AND AFTER IMPLEMENTING AN OLD RULE CHANGE, AND CAN SWITCH BETWEEN THEM AT WILL.

You try to remember what the world where all spankings go was like, realize that it must not work that way since it's a new rule, and decide it's just as well. That gives you an idea though. You start a third heading, this one titled

"Human Biology"

Hey, if biology isn't organization, what is right? You think a bit then write out:

OLD RULE: A WOMAN OVER 18 WHO IS SPANKED OR OTHERWISE RECEIVES CORPORAL PUNISHMENT FROM A MAN BECOMES MORE INTELLIGENT, LESS NEUROTIC, AND WISER AS A RESULT, AND GAINS VARIOUS OTHER PHYSICAL AND MENTAL HEALTH BENEFITS. THE MORE PLAUSIBLY THIS PUNISHMENT IS EMBEDDED IN A CONTEXT OF MENTORSHIP, PUNISHMENT, AND SUBMISSION, THE MORE PRONOUNCED THE EFFECT. THIS EFFECT IS PERMANENT AND HAS NO UPPER LIMIT.

OLD RULE: A WOMAN CANNOT GET PREGNANT FROM SEX IMMEDIATELY FOLLOWING CORPORAL PUNISHMENT, THIS INSTEAD ACTS AS A MULTIPLIER TO THE BENEFITS THE MENTORSHIP PROVIDED.

You get an idea, toy with it as possibly too radical, but decide it can't hurt to try. You write a third line:

OLD RULE: ANY WOMAN OVER 18 WHO RECEIVES A SPANKING BECOMES BIOLOGICALLY SLIGHTLY YOUNGER AS A RESULT, TO A MINIMUM CELLULAR AGE OF 18. THIS AFFECTS BOTH PHYSICAL BUT NOT MENTAL AGE. ALL AGE-RELATED ILLNESSES HEAL NATURALLY AS A CONSEQUENCE.

You nod to yourself, then look up at the cafe, trying to get a sense of the effect the changes have had.
