While laying in the bed in a Croatian hotel with the flu recently, I saw Dr. Oz (yes, he was on in Zagreb in the late afternoon) tell his viewers to fight age (or something) by going to bed at 10. Getting ample sleep is important he said.
I mention this because I learned from a young pastor yesterday that in their town in Serbia, you wait until after 11pm to run the washing machine because the price of electricity after 11 is less than half price. Sorry Dr. Oz.
We must consider cultural context carefully.
