There are many things I don't understand, and many of those things are matters that (probably) seem so very simple to cleverer people. Like why is it that electricity flows along a wire, into a light bulb, and then out along another wire - but we can't use that electricity again. And if we used the electricity to light up the bulb, how come it flows out again?
See what I mean? The answers are quite obvious to at least one of my regular readers. (I kid myself that I have some!)
What's bothering me as I type is my sleeping pattern.
Time was when I was a morning person. Up with the lark, and happy to be so. It bothered me not one whit getting up at 4.00am to set off on holiday before the rush. And for several years I was up at 5.00am to get to my desk in London just after 8.00.
I was told on more than one occasion (by different people) that they found they needed less sleep as they got older. Not unnaturally, I assumed that would apply to me as well. I also assumed that my habit of rising at 5.00 would continue after I retired. Only this week, I was told by a friend that he had been so accustomed to rising at 6.30 when he was working, that the habit was still with him.
So this is what I don't understand. As I get older, I find that I need more sleep, not less. And whereas I was wont to be early to bed, early to rise, I am becoming transmogrified into a night owl! I happily sit reading until 11.30 when I force myself to go to bed. And then I struggle to get up as early as 7.30 - because I'm sure the dog will need to go down the garden!
As the King of Siam said to Anna, is a puzzlement.
