Play your game at 2x speed. Close the game while still 2x and play another game for an hour or so.

Forget that you set two men as breeders in an effort to increase your population.

Open the game back up to find your population at 48, as opposed to the 36 you left it at.

Change the men to different skills.

Realise every single of age female has a kid. No twins this time, boo.

Twiddle your thumbs while you wait for them all to stop nursing.

:P Silly me, but it was quite fun.
