I'm going to tell you how to save the earth and still wake up in the morning.
Now that spring has arrived in the northern hemisphere, it's warmer, even in the morning. To make the morning coffee (or even tea), you have to boil water and steam up the kitchen, or maybe your whole house.
In the warmer climes, this means that you also turn on the air conditioner in the morning, and you may even accidentally leave it running all day in an empty house.
Perish the thought!
In the warm morning, it's actually nicer to have cold coffee than hot. I'm not talking about iced coffee, American style. That is a weak brew made by pouring perfectly good coffee over a half-dozen ice cubes, diluting away all the flavor.
My suggestion is to brew the hot coffee late at night. The night air is cool and opening a window will be enough to keep things pleasant. Then let the pot cool, and after 20 minutes or so put it in the fridge.
Next morning, pour a nice cold cup of strong coffee, add the usual stuff to taste, and enjoy. It simplifies the morning rush and saves electricity.

Where I Live
People ask me where I live. I'll give you a very precise answer:
This answer is correct to one part in 3 × 1068.
That number is approximately 300000000000000000000000000000000000000000000000000000000000000000000.
How do I figure this? The radius of the earth is about 6378.1 kilometers.
The radius of the known universe is about 46 billion light years. This is larger than the radius of the observed universe for technical reasons.
The volume of a sphere is proportional to the cube of the radius. The cube of 6378 kilometers divided into the cube of 46 billion light years is that 3 × 1068.
46 billion light years is 4.351843 × 1026 meters. Cubed, that is a volume of 8.24175458×1079 cubic meters.
8.24175458×1079 / 2.605498×1011 = 3.1632×1068.
This last is a very interesting number. It has nearly the same digits as the square root of ten: 3.162277. These two numbers match to 3 digits, which is more accurate than our measurements. So they could be equal.
Which proves the universe is full of coincidences.
Okay, maybe it's not a proof.
Anyway, that's where I live. So now you know.
