They weren’t actually tiny, they were about a metre long. But they do seem out of proportion.

They were very muscular and ended in very sharp talons, so pretty deadly.

I was trying to explain to an elderly friend that people don’t just phone other people now and certainly not at times they will be doing something.

She found it hard to accept that many people find it rude to be called unannounced.

As an example, at one time if someone was organising a social event (eg party) they would phone around to invite people.

But that’s incredibly rude you are imposing on someone and also asking them to decide or excuse themselves on the spot.

this is just awful, there’s something weird in his arm, his head is on backwards (or his knees and feet bend the wrong way) and there’s a strange blue thing sticking out etc etc

Not unusual at all. Everyone I know does this. Nothing wrong with you it’s just that age (and birthdays) becomes less important. Also once past a certain age you actively want to forget that you’re old, so you need to consciously think about it.

But don’t worry, once you get into your 80s it becomes a badge of honour and the older you get the more you’ll think about it.

That’s our name for it. If there is a planet or planets circling Kepler 22 they won’t call it Kepler 22.

Similarly any aliens won’t call Earth by that name. For example, Klingons might have called Earth yoSpu’bogh QongDaq until they made contact.

So aliens wouldn’t type Earth into sat nav but whatever they call it. Now that’s a showerthought !

If they haven’t visited us how will they know what the planet is called and how to spell it?

Generally, the reasons for a phone number are:

Account recovery 2FA

If you don’t want to use your number then consider a pre-pay sim. Depending what country you are in this will cost pennies per year.

I would suggest something like ProtonMail or most paid email services won’t require a number.

I hope so, good luck

Mould eats the fibres and dye, so it might be a permanent change I’m afraid. There are specialist mould removers but they might bleach coloured fabric.

As far as I know, only HDPE is suitable for vinegar. Other types of plastic react with even a weak acid causing swelling/softening.

Why does bleach come in plastic containers ? Acids on the other hand (like vinegar) come in glass containers .

Why would bleach damage it?

Photons are massless and along with other massless particles are known as Luxons because they always travel at the speed of light. But notice that the speed of light varies depending on the medium that light is crossing. (Eg 300,000 m/s in a vacuum . 200,000 m/s in glass)

So you could certainly transmit data faster than light through glass by simply transmitting it in a vacuum. But there’s little practical use except perhaps gravity wave detectors.

There are a class of particles that always travel slower than light (unless you accelerate them with infinite energy) and also a theoretical and controversial class of particles that travel at infinite speed and would require infinite energy to slow them to light speed. (If they did exist no means has ever been postulated to detect them)

That makes no sense at all.

I’d like to see the long promised redo of Control Centre and Notification Centre.

Why would it have infinite digits? It is just as like to be 0.

UK: anywhere that sells batteries has to have a disposal facility.

As well as the medical effects, there’s also the realisation (age varies when this happens) that going out in order to get drunk is not a good time.

This is true. When I checked on this about five years ago (in the UK), the cost per message was about £0.00001

With the reduction in the number of SMS sent, it now costs more to bill them. In the UK, even the cheapest monthly contract has unlimited calls and texts. There a pre-pay tariffs as low as £3 a month with calls, texts and some data.

As well as the charges issue there are three other points.

They are delivery reports not read reports.

Because of the way they are implemented they are low priority on the network and will be dropped at busy times. (This means the lack of a delivery report doesn’t necessarily mean it wasn’t delivered)

They don’t work reliably across different message centres. If you and the recipient are on different message centres, You’ll get a delivery report when it reaches the next message centre. (This means that a delivery report doesn’t necessarily mean the message was delivered)
