Secrets of your trade.

From my first job.
You can take blood samples from earlobes to measure PH, CO2 and Oxygen. The earlobe has to be well perfused and so can be warmed with Aligpan type cream.

Pacemakers do not always stop working after death.

Ooo I work in the same area op! Good for you - it's a very male dominated environment and takes a very thick skin to work in.
Here are a couple:
A bird can smash a plane windscreen - this always makes me sad for the bird.
Pirates are real in some areas of the world and there is nothing 'Disney' about them

I used to work at a theme park down south. The big rides break down almost constantly.

Also if someone throws up, we were supposed to shut the ride down, get out the biohazard masks and clean it with special cleaning fluids. Mostly we just wiped it off with wet wipes in between cycles and kept going.

Putting your kid in tall shoes/wedges so they are tall enough for rides is perfectly fine and allowed, because it means they’ll be able to touch the bottom with their shoes which is what makes it safe. Wearing a hat or giving them a ponytail does not work.

I'm sure there are more interesting secrets but I work in a hotel, our booking system has a profile of some of our guests including their appearance, what car they drive, their family history e.g 'wife died in March 2006' and whether they're having an affair

A crematorium has to 'burn' a body within 72 hours of it coming into their possession.

Ashes are ground up by a machine which is basically a mechanical pestle and mortar. Any metal (nails, hip replacments, etc) are recycled.

Im a vet nurse. If you bring your pug to us for a claw clip we take them out the back to do it so we can have them on oxygen as when they get stressed they go blue and struggle to get enough oxygen. This is because of the way they are bred to look "cute".

I used to work in research and i can tell you that fruit flies have a complex mating ritual involving serenading and oral sex

I work in a library. That security device in books that sets the alarms off if not deactivated, I can't tell you how it works but it's a great joke to try and get it on a colleague and watch them set off the alarms when they leave 😊

Mine is v boring, swimming pools. My secret is, your world will not end just because your fucking swimming pool is not working for a day

Childminders are interviewing parents as much as parents interview cms on first meetings.

I work in IT. The old switch it off and back on again sorts out your issue 9/10 times and dont tell us that you have done it cos we can see that your machine hasn't been switch off!

Teachers sometimes eat confiscated sweets and crisps if unopened packets. Back in the day we would confiscate cigarettes and smoke them ourselves. When kids give us buns, biscuits etc made in food tech class we usually "save them for later" then chuck them away because we think the kids probably pick their noses.

'Autorotation' makes it sound like there's a wee handle under the rotors in the cockpit and if all else fails you just jump up and rotate it by hand, which I'm sure is not the case and I will Google but it tickled me a bit!

Mine are boring as they are From old jobs in car insurance, car manufacture and compliance:

It's quite difficultly to cancel a policy or refuse to cover a claim. I've read so many posts on here about no mot / driving to work without business cover / having points on your license will void your cover. Also that cover is cancelled out on private property.

Even if a person walks out in front of your car and you had no chance whatsoever to stop, if the case goes to court the judge is likely to hold you at least partly liable and award the person some money.

Very few companies care that much if you threaten to take your business elsewhere.

Cars are designed to have bumpers at just the right height that if you hit a standing pedestrian, they should be lifted off their feet and on to your bonnet (this lessens the chance of shattered legs or being stuck under the car).
Some cars also have a mechanism so if this happens, the bonnet will spring slightly open at the front to stop the pedestrian falling on the floor and hitting their head.

Front seat airbags will break your glasses and likely give you burns to your face / leave you with black eyes.

Police are a nightmare to get information out of about an RTA if you're an insurer. They also are not trained in liability so if they tell you it's not your fault, that doesn't actually mean it's not your fault.

Most insurance companies are linked and owned by one big company (big example is EUI ltd owning Admiral, Bell, Diamond and Elephant)

One from DH (teacher) -
teachers sometimes take alcohol on residential trips (don't actually agree with that)

One from family member who works in TK Max:
If something isn't sold after it's been reduced a set amount of times it just gets put back to full price and moved to another store.

I want to contribute with something interesting but am struggling. I will have a think 🤔
