Congenital? No. Acquired? Yes. The area of the brain that processes and interprets sound has to develop. Without sound input as a child, that won’t happen.

Current leading theory of tinnitus is called the ‘central gain’ theory. This is where the brain becomes accustomed to seeing signals from the ear at a certain level, and when that neural level is no longer at that level it will add in its own noise to make up the difference. This noise is then perceived as a tone or sometimes a broadband sound, commonly described as either a ringing or a whooshing sound. Sometimes it can also be described as crickets. Depends on the person and cause. Not all hearing loss comes with tinnitus, but most tinnitus comes with hearing loss. In audiology school we had a whole class on tinnitus and covered many interesting aspects exactly like your shower thought here and went over papers on every angle you could think of. It was fun. But in the end, the brain has to at a minimum know what sound is to even perceive sound.

I had a CPT like that during my second deployment. He was out in 60 seconds and in the funniest positions. The team made an entire photo album of him sleeping. MK19 range included.

Thanks for the reply, I was hoping to generate more discussion. It looks like you were the only one…

Hot take here and I would love discussion- but this is a small reason why I am against a full UBI in cash, but want UBI in voucher form with only a small portion in cash. Vouchers limit potential inflation spill over from sectors and you can now control how much people are getting depending on factors to better and more fairly suit their situations. This is also why I am a huge fan of “food stamps” or food welfare programs. This is essentialy what they are doing already, just make it universal. Then we look at things like housing vouchers, another great program that we can now just scale up and make universal as well. Then you only need to give a smaller cash handout for incidental spending. You know people are going to have to spend money on housing and food, so make those the priorities for funding vouchers and you can put rules in place to minimize inflation within those industries. Then if you have people who are well of enough to not need the full voucher, let them convert the voucher over to cash at a penalty rate, say 2 to 1 for cash, or some progressive scale for remaining money. They don’t need the money as much, but you also don’t want them to be completely left out unfairly and have them resentful of the system. This could even expand into other industries or normal costs. Transportation, cable/internet, cell service, even some insurance (like car, rental, umbrella- assuming that if you are at a level of providing UBI, you are already providing universal health care). Now for each voucher you can make it needs and situation based and evaluate a fair amount for each person through an automated system depending on some quick metrics of their life. Each voucher system is also industry specific with its own oversight and regulations and inflation reductions built into it. I think it would be a better system and am open to others thoughts.

It isn’t low expectations. It is the implications of high demands. When they spec a project to last 5 flights, they are serious about that guarantee. There are so many redundancies built in the make sure that no matter the curve ball the planet throws at them, they will get their 5 flights out of it. That is on the worst case scenario side though. Then you factor in best case, and now you have things lasting years longer than their planed mission. This is how most of their projects end up lasting so much longer than planned, while also having almost every project last the minimum. Those projects minimums are all but a promise that they will do it, barring catastrophic events.

It is also more cost and time efficient. If there was a project that was going take 10 years and cost $10M with a 50% success rate and you were told ‘for each extra year and $1M-$2M we can increase that success by another 10%’ then you better believe, as a tax payer, I would be passed if they didn’t spend the extra time and money to get it up to at least a 90% success chance.

Now just scale that to hundreds of millions and billions of dollars. Some of these projects are measured in decades and take people’s entire careers. If you had a project that was 20 years of design, build, test, launch, and travel- wouldn’t you want to do some work on its ensure success?

Woosh

Ethiopia DID have a coast. It was what is now known as the country of Eritrea. They were forced to be part of the country after WW2 in 1950, and ignored the wishes of the people to remain independent. Then by 1961 a war for independence started and lasted for 30 years. It ended with the Eritrean forces taking the Ethiopian capital and winning the war capture the flag style, but with guns.

As far as Djibouti, they are probably the best example of American modern imperialism. The country enjoys a stable currency by using an American backed currency. In exchange the US has their Horn of Africa base there. Because the country is so small but the base has so many troops and the US pays to lease the land, the US military ends up making up a little bit over 10% of their entire GDP. This is the base that launches the anti-pirate operations for the region, not only providing security for Djibouti, but security for the entire HoA. Say what you want about the USA and their modern imperialism, but the only thing anyone in that region agrees with is that they love the US troops there and the mission they do.

If Ethiopia wanted to take Djibouti, not only would that piss off literally every other country in the region, they would also have to go through the USA to take it. Good luck with that.

Technically it would reach an altitude where it would become ‘null’ due to dividing by zero. You would eventually hit the vacuum of space where there is no speed of sound and any speed is faster than it.

In 2000 the Afghani was worth 75,000 to 1 USD. During ISAF occupation it was fixed at 50 to 1. It is now at 70 to 1 and dropping. Let’s stick to one argument at a time rather than playing the whataboutism game. You said the USA destroyed their economy, yet the evidence strongly says otherwise. Before 2001, Afghanistan was the second poorest country in the world. When ISAF pulled out it was ranked at about 40 (I say ‘about’ because it was still growing and changing faster and the rankings were uptated). In the short time of Taliban rule they have dropped back down to sub 33 with exact number still to be determined. (The sub 33 ranking is important because there are only 33 countries on the UN “least developed countries” list).

I would spend time debating topics like this with educated people and those that are open minded, but you do not seem like you fit either group. Do not expect a reply.

Covid actually had almost no impact on the prices and they continued to level off a little lower. The surprising one is the onshore wind remaining on par with solar and continues to drop (albeit slowely).

“Today there are about 440 nuclear power reactors operating in 32 countries plus Taiwan, with a combined capacity of about 390 GWe. In 2022 these provided 2545 TWh, about 10% of the world’s electricity.”

There have been two major reactor accidents in the history of civil nuclear power – Chernobyl and Fukushima Daiichi. Chernobyl involved an intense fire without provision for containment, and Fukushima Daiichi severely tested the containment, allowing some release of radioactivity.

Yes- a track record of one plant failing due to Soviet incompetence and political blunders; and the second failing due to checks notes a 9.0 magnitude almost direct earthquake and ensuing 133 ft tsunami.

I can see that critical thinking isn’t your strong suit, but I’m willing to comment it out with you instead of just down voting.

If the price of solar is already the lowest -and still dropping- then how is the most expensive option that takes about a decade to implement a better option for right now? This apparent point of diminishing returns is only beginning to manifest in even lower prices than this 2019 chart. And this diminishing returns point is only in the cost of the panels dropping; they are still getting better in technology and improving efficiency while maintaining low prices. If your argument is “solar can’t continue on this trend forever” -no one expects anything to consistently drop almost 90% every decade. Of course it will level out. And when it does, it will STILL be the cheapest option.

Huge up front costs.

https://world-nuclear.org/information-library/economic-aspects/economics-of-nuclear-power.aspx

“On a levelized (i.e. lifetime) basis, nuclear power is an economic source of electricity generation, combining the advantages of security, reliability and very low greenhouse gas emissions. Existing plants function well with a high degree of predictability. The operating cost of these plants is lower than almost all fossil fuel competitors, with a very low risk of operating cost inflation. Plants are now expected to operate for 60 years and even longer in the future…”

“World Nuclear Association published Nuclear Power Economics and Project Structuring in early 2017. The report notes that the economics of new nuclear plants are heavily influenced by their capital cost, which accounts for at least 60% of their LCOE. Interest charges and the construction period are important variables for determining the overall cost of capital. The escalation of nuclear capital costs in some countries, more apparent than real given the paucity of new reactor construction in OECD countries and the introduction of new designs, has peaked in the opinion of the International Energy Agency (IEA). In countries where continuous development programmes have been maintained, capital costs have been contained and, in the case of South Korea, even reduced. Over the last 15 years global median construction periods have fallen. Once a nuclear plant has been constructed, the production cost of electricity is low and predictably stable.”

TLDR: If you weren’t already on the nuke train when it was going, the upfront costs are too much to make it worth it this late in the game. You are better off just getting solar/wind + battery. If you already invested in nuke, then you are good to keep updating them.

Over the course of 20 years, the US and its coalition allies in Afganistan killed approximately 50,000 civilians and there we calls for war crimes investigations. In the course of one month Israel has killed over 10,000 civilians.

I did two tours in Afghanistan and can tell you now, they are not bending over backwards to minimize it. They are using this as an excuse to indemnify themselves from war crimes prosecution.

Death toll as of yesterday was reported around 8,000. The US/coalition 20-year war in Afghanistan was (rounding UP) 50,000. That puts it at an average of 2,500 civilian deaths per year. Even THAT number was high enough for people to call for war crimes investigations. Now Israel has reached over 3x the yearly average in only 3 weeks. On track to pass 10,000 by the one month mark, too. I’m not saying that Isreal doesn’t have the right to defend its self, or even defense through offense, but there is a point that we need to agree is too far; and I think we are a bit past it.

After rereading this in the morning/afternoon and not late night I realized my mistake. BPPV is normally the posterior, more infrequently the anterior, and to be true up/down vertigo only it would have to be both canals at the same time. The vestibular organ is odd. Either way, this whole scenario doesn’t even sound like bppv (peripheral) and is most likely something up line in the brain (central).

Go see neuro. Get an mri at least.

Unlike the othe comment, this DOES sound like it could be BPPV, where something like the epley maneuver would work. Typically we would use the Semont-plus maneuver (same idea, slightly different). Or there is a fun half somersault maneuver the person could try on their own.

Bppv will be brief but intense episodes lasting seconds with lasting nausea for minutes and exasterbated by head movements. You will also see their eyes jumping or flicking (nystagmus).
