Knew I'd see my supervisor's name in the article. The necrosis is, in some ways, the least cool reaction to their bite. Slow loris captive carers (zoo and wildlife centres) reported after a slow loris bite some developed anaphylaxis allergy reactions just being in a room with a loris. Meanwhile other captive loris care practitioners said getting bit was no worse than a bee's sting. Completely opposite ends of the loris reaction spectrum.

It was kept around because it was how banks counted coinage you deposited. You'd have little plastic money bags (remember those?) with 1p/2p 5p/10p "NO MIXED COIN" written on them, the person at the desk (or Post Office) would just weigh it to save having to count it all out!

I remember my dad explaining to me in the 1980s that ones and twos didn't count as mixed coin after I'd separated them all out into different bags!

It won't kill you at all. Because whales are bros, and won't do it when you are nearby. They will do it near microphones and such, but they won't do it with human swimmers in the water.

That said, they do a lot of lower volume clicks. Which are still powerful enough to cause serious medical problems. Which has happened.

The key word is "can". In theory. It has never happened, because although certain humans have decided that swimming right next to the largest predator that ever lived is a rational thing to do, no human has ever been killed by it.

... Because for some bizarre reason, whales like us. I am not sure exactly what we did to deserve this, but they don't do their high volume clicks when humans are in the area. They get away from humans before they resume clicking. Sperm Whales have killed a lot of people, but exclusively people that were hunting them at the time.

And that's in a holdover from when their worth was based on being of valuable metals, which was why old currency conversions seemed kinda arbitrary, manufacturing and handling determined the size and coins would then be worth whatever was the exchange rate of the material.

I work in retail design and technology and can say that, while this exists it is far from wide spread. There are many more effective and accurate ways of capturing customer data in use. One of the hard to decipher points with smart displays is that it is difficult to tell from audience reactions what exactly the customer is reacting to. Could be the whole outfit, a single item, the mannequin pose or visual merchandising elements, etc.
