Blurred vision

Vision changes with age. If you have shortsightedness it can sometimes get better because your eyeballs can shrink with age, that means the image hitting the retina at the back of the eye comes back into better focus. On the other hand the lens in your eye can start to stiffen and the muscles around it don’t pull on it as well as when you are younger. So the lens does not focus as it used to. This is called presbyopia and tends to affect people over forty (if I remember). Hence vision can change with time. Worth getting an eye test?

Cornwall

A glow in the sky

Memory of an evening walk

Across grassy fields

And over stony stiles

Only a few days

By the sea

But I remember

The hues and colours

The sights and river sounds

Blousy hedgerows

Full of blossoms

Fruits and seedheads

Mild and breezy

Candyfloss clouds

Cornwall, County of coastlines

Beautiful beaches

High cliffs and moors

I want to return.

What’s out there?

There’s something called the Drake equation that hypothesises whether there is other intelligent life out in the universe. I don’t know it and can’t quote it, but I looked it up (see above). The fact that the scientists have even found amino acids in space (the building blocks of life) means that there are possibilities of finding other beings.

The equation looks at how many possible inhabitable planets are out there, whether life could evolve, and whether intelligent life might come about. Then you have to think about time. If an intelligent life form was to exist somewhere else they might send out signals, but it could take millions or billions of years to travel across space before we detected it, and by then they could be long gone. So it would only be possible to communicate if they were closer, tens of years away? But then a conversation with someone even twenty light years away (the distance of a possible habitable planet) would be very boring. One question every forty years, one reply eafter another forty years. And space travel would only be possible at a small percentage of the speed of light, according to the laws of physics. So we might be able to talk but not visit.

It might be great to get a signal, but even if there are other civilisations it doesn’t mean we will ever find out.

North America

So yet again I didn’t know what to draw. I tried to remember the shape of the North American continent (including Canada) and to draw it from imagination. Then I remembered when our teacher would use a roller to print out the shape of the United Kingdom onto our school books for geography class. Maybe American children had something similar to use for history or geography? So that’s what this drawing is meant to be…#bandofsketchers prompt for Thursday.

Tidied cupboard

About twelve inches of paperwork removed from this cupboard, my paintbrushes stored in vases, a star mobile lit at the back of the cupboard (it’s on a cable and won’t work anymore when it’s hanging up). Two glasses of coffee liquor over ice. It actually feels quite grown up. I can also get at my orchid plants in the window, one of which I seem to have killed. I have got to finish off by tidying the cupboard next to this. I’d like to have it done by Christmas if I feel OK. Housework? I hate it. But sometimes you have to do it….

Still negative

Spending time worrying about whether I have covid means I have not really thought about all the other bugs out there. They can be transmitted differently, for instance by touching surfaces. I think covid is spread more by breathing in droplets.

Anyway, bam! I have got a bad cold or virus, and as many of these haven’t been around as much because people were not interacting or being in close contact with one another. We are all more susceptible to the risks of other diseases now. You might have immunity to one illness, but if you are not in contact with it frequently then it can be worse when you get it again. What fun! Sniffles…..
