Probably to make sure she’s not pregnant before doing the x-ray and Ct scan

Do you have some examples?

Probably because sour would make your lips pucker? I think lemons would be more obvious.

Personally I would include it just so that the next homeowner doesn’t curse you when they go to drill something into an expected stud that isn’t there.

Try threading a wood screw into the hollow pin until it grabs, and pull it out while twisting with a pair of pliers.

What happens when you wear one?

How would someone get started doing this?

This would make a good community, post news stories and have other people try to predict conspiracy theories about them!

That’s what caught my eye as well! Anyone who’s worked with qc or metrology would probably not be able to miss it.

It’s a flexible coupling for a drive shaft. It probably does show up on stepper motors for 3d printers. It’s used to allow for some misalignment between the motor and the rest of the drive assembly so there isn’t any damage to the motor bearings or binding of the shaft.
