Fun fact: the standard advice for if a dog, cat, or human bites your hand, is to feed the bite. Push your hand further into their mouth, forcing the jaw open.

Nurses, EMTs, veterinarians, etc are taught to respond this

The advice for a human biting you is to jam your hand or arm deeper into their mouth, and rub the spot under their nose back and forth.
If you attempt to remove your hand, or forearm, the teeth do what they're supposed to and gouge out a chunk.

This vicious wolf attack illustrates proper technique.
So: every EMT and nurse who gets bitten by a human, is trained to jam their hand or forearm deeper into the mouth, feeding the bite so the jaw widens enough to remove the limb
Also, every redneck learns this along with the advice of "never run from an angry dog"
People whose life involves more bites than usual, are trained to do this. They get horror stories from coworkers who forgot to feed the bite.
A study of human bites: https://t.co/7sYwaiX8Xd
The study indicates that one of the worst bite wounds from a human, is a "fight bite," where someone punches their fist right into a person's mouth. This causes very deep puncture wounds, and greatly increases the chance of infection of tendons and joints.
What makes fight bites even more dangerous, is that extending the fingers afterwards acts to smear bacteria along tendons.

They have to be evaluated while keeping the fist closed.
The natural response to hand injuries is to flex the hand, extending the fingers to evaluate the extent of the injury.

This, if the bite punctured the MCP joints or tendon sheath, makes infection much more likely.
Who gets bitten most frequently?

Young, drunk men, while partying. And they get bitten mostly on the face.

Human bite injuries account for 0.1% of ER visits.

Here's a study of bite wounds, animal and human, in Germany https://t.co/59H58rhlrq
In this study, 77% of human bites were fight bites https://t.co/mvnu5wJXja
This study measured bite force in 770 humans

Incisor: 43.3kg
First Molar: 120.66kg https://t.co/EfRbZEZjsh
This study tested human bite force using a gnathodynamometer.

All subjects ceased applying pressure citing tooth pain, well before maximal pressure was exerted. https://t.co/IRGjQxoTi5
The highest recorded bite in this one was 124kg.

He also used a phagodynamometer to test crush pressures of various foods, with surprising results. He found that bread crusts can be incompressible enough to shatter tooth cusps.
The strongest recorded human bite was by Richard Hofmann, a floridaman, with 442kg of bite strength as measured by the gnathodynamometer.

Look at some historical examples of mass psychogenic illnesses: dancing plagues, laughing plagues, meowing nuns,

Here's a video on them:

They are interesting, but what is more interesting to me is Culture Bound Syndrome.
https://t.co/hMKaApUMZn

Basically: mass psychogenic illness, and presentation of various mental illnesses, do not occur in a vacuum. Cultures shape them.

For instance, Koro.

There have been several mass outbreaks of men completely convinced their penises are shrinking, anchoring them with string at night so they don't get sucked back inside.

Almost all in Southeast

Here's a description of one outbreak in Hainan in 1984:

One theory for why the Spanish flu was so unusually lethal for young people:

They hadn't lived through the previous flu pandemic of 1889-1890 (https://t.co/OiDZYtdbWx) that killed about 1 million people. And thus had no carryover immunity.

It's suspected that the 1889 pandemic was not influenza, but a coronavirus.

The 1889 virus spread rapidly, killing mostly the elderly.

The 1889 virus was the first truly modern pandemic: people knew about germs, it spread via trains, it spread at the speed of modern transportation and commerce

Let's talk honestly about "informed consent."
Someone with decades of training gives someone with none advice usually packed into 1-3 mins. Huge amount is based on trust. Huge potential for bias built in. But also there is no obligation to provide real alternative options.


I am classified as 'gifted' (obnoxious and ableist term). I mention because of what I am about to say. You all know that I was an ambulatory wheelchair user previously - could stand - but contractures have ended that. When I pleaded for physio, turned down. But did you know...

I recently was chatting with a doctor I know and explaining what happened and the day the physiatrist told me it was too late and nothing could be done. The doctor asked if I'd like one of her friends/colleagues to give second opinion. I said yes please! So...

She said can you send me MRI and other imaging they did to determine it wasn't possible to address your contractures.

Me: What?
Dr.: They did a MRI first before deciding right?
Me: No
Dr: What did they do??!
Me: Examined me for 2 minutes.
Dr: I am very angry rn. Can't talk.

My point is you don't even know if you are making "informed" decisions because the only source of information you have is the person who has already decided what they think you should do. And may I remind you of a word called 'compliance.'

Viruses and other pathogens are often studied as stand-alone entities, despite that, in nature, they mostly live in multispecies associations called biofilms—both externally and within the host.

https://t.co/FBfXhUrH5d


Microorganisms in biofilms are enclosed by an extracellular matrix that confers protection and improves survival. Previous studies have shown that viruses can secondarily colonize preexisting biofilms, and viral biofilms have also been described.


...we raise the perspective that CoVs can persistently infect bats due to their association with biofilm structures. This phenomenon potentially provides an optimal environment for nonpathogenic & well-adapted viruses to interact with the host, as well as for viral recombination.


Biofilms can also enhance virion viability in extracellular environments, such as on fomites and in aquatic sediments, allowing viral persistence and dissemination.
