OK, OK, calm down.
So, maybe 30 million cubic meters per second isn’t the same as 8 million gallons per second. It’s a bit more. It’s, um, quite a bit more. So let’s all just relax, OK? I’ll never trust another online measurement-conversion site again.
So take a deep breath and we’ll talk about something else.
Why are my tears salty?
That’s easy. It’s because you are a bit salty yourself. If you weren’t, you would explode, sort of. Or shrivel up.
There is a little bit of salt in all the cells in your body. This, in case anybody asks, is called osmolarity. And the fluids surrounding your cells have the same amount of salt, known as isotonic.
This is good, because if those fluids had more salt, they would suck the water out of the cells, and the cells would shrivel up.
If the cells had more salt than the fluids around them, the water would pour into the cell until it burst.
OK, 1 cubic meter of water is about 264 gallons of water. You do the math. I am never doing math in this column again. In fact, I may never even use numbers again. They’re nothing but trouble. I’ll just write stuff like “a lot,” or “some” or “not so many.” That might be a good idea.
Do blind people see stuff in their dreams?
It depends. People who are blind from birth don’t see things in their dreams. Mostly, their dreams are made of sounds or emotions.
However, it is possible that someone blind from birth could see something in their dreams that had been very vividly described to them – a construct of that item, so to speak.
People who lose their sight later in life see things in their dreams, but as they were when they lost their sight. I am told, for instance, that if your brother was 15 (drat, a number) when you lost your sight, you might see him in your dreams years later as he looked when he was 15.
When we are not using our laptop computer, my husband says it should be turned off completely. A friend whose career has been in computers says to just close the lid and let it “hibernate.” Which is it?
As I understand it, when your computer hibernates, it saves whatever you were doing at the time in a special file on the hard drive and then shuts down. When you start up again, you’ll be right back where you were.
