Don’t let the door hit you on your way out.

Woman can only give birth every year.
A single man on the other hand might impregnate women each and every week, from maturity till his heart stops beating.

So woman held considerable power in any society and it would only be natural for men to seize the means of reproduction.

I think that’s what happened, historically speaking.

Every third shift is an undesired shift.
I arranged my six weeks of time off accordingly spread evenly around the year.
Now the undesired shift gets postponed and I have to tske that in account too when making long term appointments.
