How old are lorry trailers before they generally retire?

Or can they be updated/refitted to prolong their life?

Like anything else, depends on use
A trailer that's loaded/unloaded 3 times a day, all short journeys, will be knackered long before one that does 2000km a day along the autobahn, but generally would be somewhere between 5 and 10 years, then sold on to cheaper places or just scrapped

Or dumped in a field next to a motorway with an advertising hoarding.

Datum plate - explained on this link http://www.railsigns.uk/info/other1/other1.html

That looks like it! Datum plate.

Thankee.

I've infused some gin with clementines and added sugar. Will the alcohol percentage go up, down, or stay the same? It tastes good btw.

I currently work with a Kerry, used to have a customer called Vivienne and years ago used to work with a Stacy, all of whom are men.

While not doubting you for one second, are you sure
that the customer didn’t spell his name as Vivian?
Alfred, Lord Tennyson’s “Lady of the Lake” was Vivien.

I know that there will be a simple answer to this. My parents flew from New Zealand to America. The pilot came over the tannoy and said we have just crossed the international date line today will be Tuesday again! So they had the same day twice?! Like the day gained in Round the World in 80 Days. So technically they have lived a day longer than me but aren't because of the days away. Messes my head.

Or

They’ve lived a day less than you, having missed (your) Wednesday and having to redo Tuesday for their sins. If they came home the same way (as opposed to going right around) they would recross the date line and jump ahead a day, never get Wednesday back.

I once flew out of Sydney on New Year’s Eve, was awoken a bit later by the crew to celebrate with champers etc., landed in LA the day before and ended up having New Years Eve again.

Surely Rafe rhymes with safe, but Ralph doesn't ?

I was thinking of Ralph Vaughn Williams whose first name is regularly pronounced Raif [ Rafe ].

Older. You age faster out of earth's gravitational field (general relativity). You age more slowly when you're moving (special relativity), but general wins out over special (unless you're moving at a significant percentage of c).

I don't think any of us will miss a few seconds due to Einsteinian physics unless those few seconds coincide with an impending vinegar stroke ( not to be confused with either 2 or 4 stroke internal combustion engines). You could, of course, also have a non- reciprocating wankel engine - reliant on a different stroke, altogether.

Presumably you must have been in the same location as at least one of your parents at some point in the past, so if they've gained a calendar day on that flight, they'd already lost one, or you'd gained one, at some point in the past.

If you really want to mess with your head, remember that they will have aged slightly less than you during the duration of the flight due to time dilation as they were travelling faster. It's a pretty small effect though, the International Space Station gains something like 1 second every 50 years and it's going a lot faster.

Try explaining yo yourself - and me - the meaning of the Equation of Time!

https://en.wikipedia.org/wiki/Equation_of_time

It's the reason the latest sunrise, the shortest day and the earliest sunset aren't all on the same day. It is also something to do with the fact that the Earth's orbit isn't a perfect circle - I think.

Gravitational time delation Vs general relativity time dilation.

Anyone able to work out the intersection of time dilation off these two theories? Gravitational force as well as speed variables make it a bit beyond me today!

Doubt away, as I am not sure in the least.

It probably was Vivian, if that is the way the male version is usually spelled.

Thank you for bringing the error to my attention, I shall edit my initial statement.

How do targeted ad's work? I'm finding that my youtube/facebook suggestions are coming up with stuff related to conversation topics I've had, but more so than anytime previously.

I've turned off my microphone on the phone for everything and the same for my wife. The people I talk to are not on my facebook so has something changed in this area to get through that?

Maybe I need to invest in some more tin foil

"They" do seem to be listening. I can't remeber what it was, but I was talking about something the other day and suddenly had ads for it. I've also been talking about something, and when I went to Google it, it came up as the first suggestion when I started typing. I used to take the pi$$ of my wife putting a plaster over the camera on her tablet saying she was paranoid, but I think more and more we are being observed, maybe not visually, yet, but certainly conversations seem to be triggering ads.
