Ken decides to change the gender ratio a bit. Looking through the book he finds that the male to female ratio is around 50-50, he changes that so the ratio becomes 10-90. Woman are now more more in number than men.
Just so nothing unexpected happens he carefully looks at the gender dynamics page and finds that it is now common and acceptable and expected for a man to have multiple wives. Because of the scarcity in men, men are also subject to a better social standing as well. Ken changes the settings to make men taller, stronger, and smarter while woman are smaller, sexier and more obedient. Men make up most of the managers of this world while woman make up the workers.
Ken feels the world change and begins to remember his three hot girlfriends he has at school.
