They still want to have sex with sexy people, and many people, when they're in the mood to have sex with sexy people, don't want to use protection. And some of those people who were not in the mood for protection also don't have access to abortions, and some others actually want to raise children by themselves for some reason. This is the actual process of human natural selection, and it's not much influenced by laws…

> and many people, when they're in the mood to have sex with sexy people, don't want to use protection. I don't believe not using a condom with a Tinder date is an option, at least in the West. No matter how attractive and insisting the male is, a woman knows she is the one to bear the consequences. Even if they're on a pill, STDs are still a thing, so why take the risk.

> I don't believe not using a condom with a Tinder date is an option, at least in the West.

It's a very common option. About 30% report non-use of condoms in their previous one-night-stand.

Most STDs are minor and/or easily treatable diseases. The worry about them has a huge moralistic component.

"Collectively, these observations suggest that increased cerebral oxidative stress following prolonged apnea in trained divers may reflect a functional physiologic response, rather than a purely maladaptive phenomenon." so, this paper neither is relevant for seal training nor does it claim any harm caused by breath holding, based on the Abstract section.

yeah, maybe this paper isn't the most relevant source. hopefully you can find a better one if learning about this is important to you, i suggest reading the papers it references, or related papers in google scholar. i'm super not motivated to help you right now because you're acting like if you're wrong about something it's my responsibility to convince you this kind of bullshit is really frustrating. my comment alre…

well, i read plenty about breathing techniques and training from various angles and also practice breath exercises where hyperventilation and breath holding play key roles. i never came across anybody claiming that holding your breath especially pre-fainting (which is essential when practicing apnoe diving - and btw you seem to confuse apnoe with sleep apnea?).

to add something of substance - here is a study that does not even find any "Link between Repeated Transient Chokes and Chronic Traumatic Encephalopathy Related Effects" and that kind of asphyxiation is obviously much more extreme than holding your breath.

That’s about apnea though. Don’t seals mostly do scuba diving? Or are they really holding their breath?

Some have died from doing underwater breath holding training [1] but I don't know how many minutes they aim for or how regular that is. [1] https://www.detroitnews.com/story/news/local/michigan/2015/1...

technically they didn't die _from_ doing underwater breath holding training _directly_. they fainted (the question at hand is - does the training up to this point cause brain damage) and then drowned.

A lot of special forces have been doing what we used to call "door kicking" in the last few wars. Lots of explosive breaches, firing weapons and throwing grenades indoors. I'm sure this is the main contributing factor. The percussive force of firing and explosives indoors is horrible and I say this as an ex artillery officer, so I'm used to chest-breaking bangs from firing big artillery guns

Rifles would never do this. They probably usually/always wore ear protection during training. Even if not it wouldn't do it. Many civilians fire guns throughout their lives, often without ear protection. This would take a much bigger explosion.

If you have been firing a whole day, you definitely fell funny in the head. Ear protecting does not protect brain much. It protects hearing. Brain heals from very mild damage when there is time to rest, but when you shoot all day, day after day, the damage can accumulate. One already recognized problem area is the show wave getting between helmet and skull. It can amplify the impact. Nobody knows what the impact from…

Modern combat helmets don’t leave a “gap” between head and helmet, the “gap” is filled with padding to absorb impact/shock and improve comfort.

Famously the Navy SEALs' entry exam-slash-basic training is named "Basic Underwater Demolition/SEAL" as a carry-over from its WWII Underwater Demolition Team legacy, maybe GP is referring to that?

I wonder if the Havanna syndrome is somehow correlated with this as well

There was a rather scathing study on it here. [1] In short the government's own internal investigations realized the obvious answer, a mass hysteria event, was the most likely culprit. But politics got involved and so then they classified reports mentioning this, and released reports suggestive of foreign adversaries attacking people with some mystery weapon, even though their own internal reports put the chances of…

That doesn't read like science, it reads like an ideological statement. The current punishment for scientific fraud is non-existent and academia is full of it and ideologically driven pseudoscientific research.

Subsequent evidence debunked that "post-mortem", as another user posted.

We've seen, with evidence, China pressure research groups and Nature into calling the lab leak hypothesis a conspiracy theory. Like "fake news", "conspiracy theory" is now actively used by China as a way to shut down evidence.

From subpoenaed communications we even know that certain figures who publicly denounced the lab-leak theory as a conspiracy, privately believed the theory was likely.

Government covert operations are not the kind of phenomenon science can properly study because it's not reproducible and data is not open. It's the realm of investigative journalism and intelligence.

This blatant mysogyny is shocking so out in the open. There's nothing "cowardly" about asking a woman to protect her country, or her husband. Not that I support the idea of drafting civilian populations as soldiers in general: it's mostly a way to get innocent people killed and not much more.

I think you mean misandry. Perhaps it is. Men bear the burden of conflict. Women bear the aftermath. But that’s how things shake out due to biology. Same as we frown upon sending children to war. Yes, they are easier to indoctrinate and can pull a trigger just as well as adults (see today’s conflict ridden areas of Africa). Yet, we know better than to send “future us-es” into the grinder guaranteeing societal collaps…

No, I do mean misogyny. Women are just as capable and willing as men to fight and defend. With modern weapons especially, there is no real difference between the fighting capacity of a woman and that of a man. And women are people in their own right, not things to be protected to perpetuate society.

Also, women are not children. Children deserve protection because they don't know any better, their minds are not fully equipped to understand what going to war means. Additionally, children make very poor soldiers, as their motor skills and reasoning skills and emotional control are just not developed enough to function as well as an adult, particularly in times of extreme stress such as war.

So again, children require and deserve protection from the rest of society. Women neither require it, nor deserve it, not any more than any other civilian.

i am specifically not talking about sleep apnea, which everyone already knows causes brain damage
