What are those floaty things in your eye? (TED-Ed lesson)

Fairbs says...

Sorry to hear that. All the time? I take it there's no way to fix? Sounds kind of like some sort of eye trauma.

Mine are like this in both eyes:
http://www.barransclass.com/phys1090/circus/Gillespie_B/EyeFloaters2.jpg

I got them all 15 years ago when an insanely powerful flash discharged right in front of my eyes. (INSTANT pain ON) Over the next few days my eyes filled with them.

When I look at highly collimated light (like a powerful view in a microscope or telescope) I can see ALLLLL of them swimming in 3D.

A bright sunny day blue sky is like looking through egg whites.

Happened across this while looking at avalanche videos

if you're interested,....

generally you wear a transceiver (sometimes called a beacon). Everyone wears one and it constantly transmits. If someone gets buried , the rescuers switch to search mode. Old transceivers just beeped faster as you got closer, but modern digital transceivers generally have a distance and direction readout. They're still only good for about 100 feet.

You have 15-20 mins to dig someone out before Bad Shit happens (oxygen depravation, etc). The digging itself takes most of the time, so finding them quickly is imperative. All of which assumes they haven't already died of trauma in the initial slide.

Driver Tailgating a Cyclist Gets Instant Justice

Payback says...

So many cyclists are unbelievable assholes too. 95% have no clue what the laws regarding cyclists are, and 95% of those couldn't care less.

All the times I've seen a cyclist become road pizza, they've either been doing something stupid, or making a foolish assumption they're in the right because they aren't doing something stupid.

Being in the right on a bike is only good for chatting up the hot trauma nurse, or a decent start for your eulogy.

One of the very rare times they're there for you when you need them. Thank goodness.

So many pricks are such unbelievable assholes to cyclists it blows my mind.

I vehemently disagree with the sentiment that she's a bimbo for being distraught over suffering medical trauma, non-life-threatening though it may be.

For those animals to just laugh at her disgusts me.

Mother of Four Cures PTSD With MDMA

Trancecoach says...

First of all, you're confusing remorse/regret with post-traumatic stress disorder. They're not the same thing.
Secondly, military soldiers aren't the only ones that experience PTSD.
And third, you seem to have a misunderstanding of what constitutes "trauma," and ways to treat it.

billpayer said:

If you go to war and kill people you are actually SUPPOSED TO FEEL BAD FOR THE REST OF YOUR LIFE.
No amount of Ecstasy is going to change that.
The idea of 'Curing' that kind of Trauma is ridiculous.

reactions to the mountain viper fight GoT - spoilers

harlequinn says...

I watched it carefully. His arm moves very fast for a dying man. Keep in mind, I think they set the tone of Oberyn's amazing speed and reaction time when they first introduced him and he nailed that guard's hand to the table. So I would have liked them to persist with that (as in, fast as the Mountain was he would still be too slow)

Being run through with a huge bladed spear twice will inflict massive trauma to a very vascular region, creating immediate blood loss and very quick hypovolaemic shock. I agree that you can keep going until your blood pressure is low enough to knock you down (I was a paramedic - that's bread and butter stuff for me). But he already fell down involuntarily. If he made a massive adrenaline fueled exertion after that I expect to see rainbows of blood coming out of the Mountain (for the viewers pleasure of course) and for you to be slower (you've got blood loss! - which doesn't speed you up).

As I wrote I haven't read the books, so a lot of the nuances will be lost on me (and other unenlighted).

I would have dropped the emotion and instead pushed the cockiness of Oberyn and let that be his downfall (and you could have almost the exact same ending).

I understand in the book the Mountain is like 8 feet tall. This would have helped with the skull popping effect (which is not possible by even the strongest men in our world). And it would have made it look cool with a veritable giant next to Oberyn.

Chairman_woo said:

I also don't see how you can describe the mountain as a "super ninja" here. Everything he does at the end is an exercise in brute strength, let's not forget he's wearing mailed fists, the blow to the mouth need not be especially strong or quick to do the damage. All he does after that is roll on top of him with the last bit of strength and rage he has (spurred on by his "beetle crushing" fuck everything mindset). Subsequently crushing the skull has more to do with his upper body weight as his hands alone.

A massive strong man yanks someone's legs out from under them, punches them in the mouth and then climbs on top (while they are stunned) to finish the job.

Being run through doesn't necessarily stop one's muscles from working until the blood loss kicks in. Doubly so with the adrenaline of a life or death fight (and the anaesthetic effect massive trauma has on the nervous system). There are countless stories of soldiers and criminals being mortally wounded by multiple shots to the chest who continued attacking till the blood loss overcame them. Gregor Clegane is exactly the sort of psycho who might exhibit such bloody minded behaviour.

I might also remind you that the Mountain has one more than one occasion been described as "swifter than might be expected for a man of such stature" i.e. not a lumbering hulk. He gets several blows in on Oberyn during the fight. Many of the swings are extremely heavy but they are calculated moves from an expert fighter who is more than capable of moving quickly when needed.

Oberyn is quicker, but the Mountain is not exactly slow (that's one of the reasons why the Mountain is/was formerly undefeated, he's big but can still move relatively quickly for his size).

reactions to the mountain viper fight GoT - spoilers

Chairman_woo says...

This scene is pretty close to how it goes down in the book, save a little variation in how the final blow is administered.

I also completely disagree, I think the director completely nailed it. It plays up to a lifetime of predictable cliché's only to turn them right around and give us a dose of cold hard reality.

Hero's frequently loose, villains frequently win, overconfidence is a weakness and having a just cause is no guarantee of victory.

Oberyn wins the fight but allows his need for vengeance to cloud his judgement. He starts calm and works himself into more and more of a frenzy over a neurosis he has carried for many years. IMHO this was portrayed pretty authentically, he starts calm (as he has learned to be) but as the fight progresses he allows the guard to drop and the raging emotions to manifest properly.

Now he can afford to let these bottled up feeling out properly, the mountain is right there and soon he will kill him! Throw in some adrenaline and the anticipation of that moment overwhelms the self control that earned him the title red viper.

That's fair enough. I haven't read the books but the tv version butchered this scene in so many ways.

Up front note: nobody should be surprised Oberyn died - it's GOT - it's to be expected.

That said, I wish the director wouldnt have.... Oberyn (an experienced fighter) be cool as ice before the fight just to turn into a emotional wreck a few seconds into the fight.

Don't show us the Mountain as a lumbering hulk who then, after being fully run through with a spear twice and having a calf slashed, turn into a super ninja while Oberyn makes a beginners mistake and turns into a sloth.

The director going comic book bad guys on us sucked.

Edward Snowden NBC News Full Interview

Xaielao says...

"... disingenuous for our government to exploit the national trauma that we all suffered together and worked so hard to come through, to justify programs that have never been shown to keep us safe, but cost us liberties and freedoms that we don't need to give up and our constitution says we should never give up."

It's funny that Williams brings up pearl harbor. We over-reacted to that too by forcefully imprisoning tens of thousands of US citizens because of their race alone. Something they've worked hard over the last 60 years to remove from public consciousness.

The idea that they give a fuck about you or your constitutional rights has been proven false repeatedly if they have an inkling of an opinion that you or someone 3 steps removed from you has done something they don't like, illegal or not.

Fuck The Poor

shoany says...

While I see where you're coming from, I have a few issues with what you're saying:

1. The organization you're referring to is staffed, has offices and overheads. Assuming it isn't corrupt and skimming and holding multi-million-dollar appreciation nights and galas (and we probably shouldn't assume that it isn't), the money you're giving this organization still gets portioned off quite a bit. Your point about helping on the systemic level is quite valid (provided you are channelling your concern into actually doing so), but I'd look more into local community health centres or the nonprofit down the street, and still, that money isn't guaranteed to reach the person in front of you. Much as a social worker can help him connect to essential services, advocate for fair and affordable housing, counsel him on trauma, etc, he will still need money for a lot of basic needs.

2. You are vastly oversimplifying the needs and situation of every person on the street. That person may actually depend on money from strangers to make rent (being that welfare barely puts a dent in even the lowest affordable housing costs), feed kids, buy food that isn't McDonald's or canned food, get a haircut, or a million other things that everyone needs money for.

3. Even if that person intends to spend some of your money on oxy or crack, it is not in your right to judge that. While addiction can very generally be called "bad", this person may suffer from chronic pain, trauma, mental illnesses, or some combination and short of governments finally realizing that housing and caring for the poor is cheaper than incarcerating them and treating emergency health conditions, self-medicating is the only reasonable way they can continue functioning for another day. This isn't even an unlikely scenario; think how easily someone can go from your (or my) comfy life to homeless, poor and desperate. It isn't always "bad decisions"; you could be a contractor that falls and gets a serious injury, hit by a car, stricken with a mental illness you have no control over, traumatized earlier in life, born into a high-risk environment or social strata, or anything else, and then start sliding from there. You develop an addiction, your income comes to a screeching halt, your loved ones can't or get too tired to support you, bills that were routine become suffocating, and there you are on the street, pain exploding relentlessly in your body/mind, on the other side of the decision, seeing chins turned up and eyes turned away from you and hearing people mutter "Don't give anything to him; he's just gonna use it to get high," to each other.

4. Not a single person in the video (and really, in just about every situation you see on whatever street you're on) speaks to or even looks at the guy.

While I wouldn't expect that everyone gives money to folks on the street (I myself have only done it a few times), it frustrates me to hear people insist that nobody should. "He's just going to use it for drugs/booze" is a presumptuous and ignorant statement and mindset.

One more thing: if you really care about urban poverty and those suffering from it, the biggest thing (IMO) you can do is vote for politicians/parties who openly and strongly support social services and welfare, then hold them to their promises. I don't make a ton of money, but I am happy to pay higher taxes and lose some luxuries if it means people who need help just to get by get it.

Fausticle said:

Exactly, a lot of the time giving money on the street is counter productive. It's best to give it to an organization that can make the most use of that money to help people. The majority of people begging on the street are either mentally ill or addicts and they need more then just a couple of bucks to get another fix they need real help from the community.

Health Care: U.S. vs. Canada

chingalera says...

Hey, as long as the no-waiting includes semi-emergency services akin to and with the predictability of the ethics of trauma center care for cost-prohibitive percutaneous coronary intervention, they can bill me...I simply may not be able to pay all at once, but I'll guarantee with confidence and a certainty from experience that I won't get turned-away from the table, with or without insurance. If we have to, and taking a cue from the fine United States citizens bordering our neighbors to the north, we'll simply stroll into Canada-

Everyone's gonna go someday until we don't have to unless we choose to and the alternative to the flesh dying and that kind of longevity probably won't happen for at least a hundred years or more....Timing. Almost everything.

Ellen Page Announces She's Gay At Las Vegas H.R. Conference.

The "it" that's about JS are fucking insane law-masturbation in Idaho and the inane in both camps duking it out to get their way. Like I said, 14-year-old girls kicking and screaming to have it the way they want it. Dude, it's fucking Idaho-Some of the most back-assward fucks from all over the country have relocated there to get the fuck away from everyone else and their bullshit, as they see it.

Think Utah when Joe Smith skipped the Northeast except with redder necks than clansmen with a history of blunt-force trauma to the head.

Ellen Page Announces She's Gay At Las Vegas H.R. Conference.

JustSaying says...

Exactly, you didn't get the point. It isn't about punishing people for being hypocritical idiots, it's about calling them out for it and making clear that behaviour isn't ok.
Let's stick with the wedding cake example for a moment. It's not about forcing somebody to make a shitty cake a dozen other people can do as well or having them pay damages for percieved (by lawyers or pissed off grooms) emotional trauma. I would be perfectly fine with it if a judge ordered those kind of businessowners to just hang some Westboro Baptist style posters on their storefront and call it a day. At least then everybody knew with what kind of people they're dealing with.
The problem isn't that people with shitty opinions exist, they'll be always there, the problem is if we let them act as if it's normal and fine and not adress it.
You would crucify them if they'd say that sex with children is ok, you'd call them out if they were telling you black people should be glad their slave ancestors were treated so well. Shit, just try to open a mosque one block away from ground zero and someone will talk to you about that too.
Why is it wrong then if you confront them when they put gay relationships on the same level as people fucking their dogs or tell us that two fathers can't raise a son?
I was serious when I said I admire the Phelps familiy for their honesty. They're horrible, disgusting people but at least they made up their minds and stick to their beliefs. They won't come to us calling homosexuality a "controversial lifestyle" where you can have "differing opinions" than all the "gay friends they have". You fuck a bloke in the ass you go to hell, that's it. No cures, no dicussions. It's antisocial, cruel and stupid but at least, they very least, it's honest.
Those anti discrimination laws are just crude tool to protrect yourself from their stupid hatred. Not everybody lives in San Francisco where you call your transgender girlfriends for a protest sit in at the local homophobic bakery. Some people have only big brother on their side in their hometown.
It's not about getting your way, it's about stopping others from continuing taking a shit on you.

Ones' the kind of asshole that reserves the right to refuse service to someone for any reason whatsoever and the other is a type of asshole that reserves the right to sick the laws on you, sue you because the law is so fucked-up that it will let those assholes do that...I don't get your point.

Uncreative, self-centered pricks are everywhere, regardless of race, creed, color, or fucking intelligence as a whore with their fractured egos in the personality's driver's seat.

Can You Imagine Living Without Cats?

My_design says...

No trauma, don't hate them, don't love them. Would be perfectly happy without them. But I'll let them stay...For now. Except for the scary big ones in western Australia. Those bastards need to go. Someone put a giant laser pointer in space and make them all run into the ocean/off a cliff. Thanks.
