At least half of men don't wash their hands before leaving a public restroom. Literally everything is covered in dick stuff. Source: 30+ years of using public restrooms as a male.

Here's a fun one

You know how you go to the public pool and you smell the chlorine keeping the water clean? That's not chlorine you're smelling.

Chlorine is a great sanitizer but when dissolved in water it has almost no smell. However, chlorine binds to organic substances like dead skin cells and especially strongly to urea (aka pee), forming chloramine. Chloramine has significantly less sanitizing capability than chlorine, but it has a very strong chloriney smell.

You can get rid of chloramine by 'shocking' the pool- adding an oxidizer or increasing the chlorine level very high to what's called breakpoint chlorination. Shock powder is expensive though so it's not always used as often as it should be.

So when you go to the public pool and you get that strong chlorine smell, all that means is either the pool water is dirty and hasn't been shocked in a while, or someone peed in the pool recently.

Enjoy your swim!

nah no way because my town heavily chlorinates the tap water and that shit reeks like a swimming pool... or is someone pissing in the tap???

My wife was so mad at me when I explained this to her. She said the chlorine smell would give her nostalgia and I ruined it.

A man's penis is generally cleaner than his hands, because his dick is kept behind two sets of fabric and isn't used to touch nearly everything.

The article below this is

Donald Trump says that if wins the White House, he'll fire special counsel Jack Smith “within two seconds” of taking office.

Imagine a criminal openly admitting he’ll use his power to evade justice, and somehow half the country is still voting for him

Neuroscience shows that rulers will always become evil.

Getting more power actually changes your brain, suppressing your ability to use empathy. The very powerful will always struggle to remember that others are human and don't want to be hurt.

Humane behavior and hierarchy are mutually exclusive. Heirarchical organization encourages humans to hurt each other.

[-] eightpix@lemmy.world 6 points 5 hours ago

The data is skewed. All of the functioning systems we use reward concentrations of power.

Thereby, systems of rule must distribute power and contest the concentration of power. It literally takes a village to save us from ourselves.

David Graeber and David Wengrow introduced me to historical examples of non-hierarchical societies in The Dawn of Everything.

[-] Hegar@fedia.io 1 points 4 hours ago

The fact that power results in antisocial behavior has been understood for millenia.

Lots of societies have had cultural infrastructure of equality that attempts to mitigate this weakness in our biology and prevent harmful levels of power accumulation. The basque village layouts that Davids Graeber & Wengrove talk about, or the practise of 'insulting the meat' of successful hunters.

Eyeing my geometry set suspiciously

At birth there are usually more males than females. Around adulthood age they are roughly equal, and around our death there are way more females than males.

Another one, kinda romantic as well. Most life long couples, when one of them dies due to old age, the other one follows soon. Despite women having a longer life span than men.

Another interesting one, most relationships end within 7 years. Once the 7 year period has passed, the likelihood of that relationship lasting till death increases significantly. It's called 7 year ick.

I wash my hands before I piss because my dick is the cleanest surface in that bathroom. Touch nothing afterward without a paper towel barrier

‘Was there anything else on the dinner menu?’

‘Vole-au-vents and Cream of Rat,’ said Gimlet. ‘All hygienically prepared.’

‘How do you mean, “hygienically prepared”?’ said Carrot.

‘The chef is under strict orders to wash his hands afterwards.’

The assembled dwarfs nodded. This was certainly pretty hygienic. You didn’t want people going around with ratty hands.

I have bad news, most (?) paper towels, toilet paper, and even the toilet seat covers are microscopically transparent, meaning there are plenty of gaps for microbes to get through.

[-] protist@mander.xyz 3 points 5 hours ago

Paper towels folded over on themselves absolutely create a barrier between my hand and the door handle. I'm not talking about flushable paper or toilet seat covers

[-] AmbiguousProps@lemmy.today 2 points 4 hours ago* (last edited 4 hours ago)

Paper towels are able to absorb water because of cellulose's natural gaps and spaces:

Most bacteria are about 1 micron, and these gaps range from around 1-10 microns.

Especially if damp, it can be argued that they don't stop the transfer of bacteria. It's possible that your bacteria transfers through it and vice versa. This is all before the fact that paper towels can already harbor bacteria on their own.

That being said, paper towels do block some. You just shouldn't think of them as sterile or a magic blocker for bacteria.

[-] protist@mander.xyz 3 points 3 hours ago

I'd be interested to culture petri dishes off my hand after I use a new paper towel to turn off the faucet vs grabbing the wet handle with my entire hand and shutting it off and then drying off my hand...

[-] bizarroland@fedia.io 30 points 9 hours ago

I don't think I'm ever going to forget, I went on a road trip and when I was in Arizona stopped at a rest stop and took a leak and washed my hands afterwards.

This native guy walked in, and I only call him out for being native because I'm native also so it's kind of cool to see another one in the wild, and he immediately said, "Get some poop on your hands? I only wash my hands when I get poop on them."

So yeah, I never touch anything in a bathroom without like at least a paper towel between me if I can avoid it

At least half of men don't wash their hands before leaving a public restroom.

How does this work in the US? I'm assuming with the amount of gigantic pickup trucks and guns, a lot of guys require tweezers and magnifying glasses to find their dicks

Do they wash the tweezers?

[-] aaron@lemm.ee 13 points 8 hours ago

Really well done. Creative and informed. Yes, we have tweezer-washing stations and very few men use them. Good question.

If a nuclear missile is launched at the United States the President has just 6 minutes to come to terms with that and decide to launch a counter attack or not.

If that counter attack is headed to North Korea, any land based missiles will head over the arctic circle, over Russian airspace where similar shoot/no shoot decisions will have to be made in a similar timeframe.

[-] tal@lemmy.today 34 points 9 hours ago* (last edited 9 hours ago)

If a nuclear missile is launched at the United States the President has just 6 minutes to come to terms with that and decide to launch a counter attack or not.

US nuclear deterrence in 2024 doesn't rely on launch-on-warning, but on the expectation that no hostile power has the ability to locate and destroy the US ballistic missile submarine fleet prior to them performing their counterlaunches.

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

In nuclear strategy, a retaliatory strike or second-strike capability is a country's assured ability to respond to a nuclear attack with powerful nuclear retaliation against the attacker. To have such an ability (and to convince an opponent of its viability) is considered vital in nuclear deterrence, as otherwise the other side might attempt to try to win a nuclear war in one massive first strike against its opponent's own nuclear forces.

Submarine-launched ballistic missiles are the traditional, but very expensive, method of providing a second strike capability, though they need to be supported by a reliable method of identifying who the attacker is.

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

Launch on warning (LOW), or fire on warning, is a strategy of nuclear weapon retaliation where a retaliatory strike is launched upon warning of enemy nuclear attack and while its missiles are still in the air, before detonation occurs.

In 1997, a US official stated that the US had the technical capability for launch on warning but did not intend to use a launch on warning posture and that the position had not changed in the 1997 presidential decision directive on nuclear weapon doctrine.

This non-reliance on launch-on-warning is also true of the French and British nuclear deterrents -- the British don't even maintain a nuclear arsenal other than on subs, so they haven't even bothered with maintaining the option to do so, and the French only use tactical ALCMs in addition to the strategic sub-launched weapons; those weapons probably would be poorly-suited for such a role.

The Brits rather famously have the "letter of last resort".

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

The letters of last resort are four identically worded handwritten letters from the prime minister of the United Kingdom to the commanding officers of the four British ballistic missile submarines and stored on board of each. They contain orders on what action to take if an enemy nuclear strike has both destroyed the British government and has also killed or otherwise incapacitated both the prime minister and their designated "second person" of responsibility, typically a high-ranking member of the Cabinet such as the deputy prime minister or the first secretary of state. If the orders are carried out, the action taken could be the last official act of His Majesty's Government.

If the letters are not used during the term of the prime minister who wrote them, they are destroyed unopened after that person leaves office, so that their content remains unknown to anyone except the issuer.

Process

A new prime minister writes a set of letters immediately after taking office and being told by the Chief of the Defence Staff "precisely what damage a Trident missile could cause". The documents are then delivered to the submarines in sealed envelopes, and the previous prime minister's letters are destroyed without being opened.

In the event of the deaths of both the prime minister and the designated alternative decision-maker as a result of a nuclear strike, the commander(s) of any nuclear submarine(s) on patrol at the time would use a series of checks to ascertain whether the letters of last resort must be opened.

According to Peter Hennessy's book The Secret State: Whitehall and the Cold War, the process by which a Vanguard-class submarine commander would determine if the British government continues to function includes, amongst other checks, establishing whether BBC Radio 4 continues broadcasting.

In 1983, the procedure for Polaris submarines was to open the envelopes if there was an evident nuclear attack, or if all UK naval broadcasts had ceased for four hours.

Options

While the contents of these letters are secret, according to the December 2008 BBC Radio 4 documentary The Human Button, there were four known options given to the prime minister to include in the letters. The prime minister might instruct the submarine commander to:

  • retaliate with nuclear weapons;

  • not retaliate;

  • use their own judgement; or,

  • place the submarine under an allied country's command, if possible. The documentary mentions Australia and the United States.

The Guardian reported in 2016 that the options are said to include: "Put yourself under the command of the United States, if it is still there", "Go to Australia", "Retaliate", or "Use your own judgement". The actual option chosen remains known only to the writer of the letter.

Heres two:

The ratio between cells of your body that belong to you vs. cells on or in your body that are microorganisms is about 1:1 — slightly favouring the bacteria.

If the Sun were destroyed, we would not know about it until more than 8 minutes after it happened.

Would someone here care to share what they know about prions?

So you know how you have dna? Well dna converts into amino acids and long chains of amino acids are called proteins. Proteins are the real workers in our body.

But you might think, if you knew the dna sequence, you know it all, correct? Not really. You see, dna is only 1 dimensional data. A lot of the information about the functions of a protein comes from its structure.

So really, if you have a correct dna converted into amino acid chain (a protein), it still needs to be in the correct shape or folding in order for it to function.

Prions are incorrect foldings of amino acid which obviously do not work. But whats more is that, when these folded structures come in contact with other functioning proteins, they can turn them into incorrect folding as well.

Since these proteins are still your own (ie they still came from your dna) the immune system doesn't quite work on them like it would on a foreign substance like bacteria or virus.

[-] WolfLink@sh.itjust.works 5 points 4 hours ago

To add to how scary prions are, you can’t really cure them, and when the prions get on a surface, it’s extremely difficult to sanitize that surface in a way that will destroy the prions. A lot of techniques that kill bacteria or even viruses like alcohol won’t work on them. Heat works but you have to make it extremely hot, much hotter than what’s needed to kill something like a bacteria.

[-] eightpix@lemmy.world 4 points 5 hours ago

I'm glad someone put the prions in here. As a biology student, there was only one thing more terrifying than retroviruses — prions.
