Waching daily Nov 24 2017

This video is part of an exciting collaboration with second thought.

Make sure you watch their video after this one.

The heart is a vital organ in the body.

Usually people are pronounced dead when their heart stops beating.

So, what if we didn't have one?

Hello and welcome back to Life's Biggest Questions, I am Rebecca Felgate and today

we're asking, can you live without a heart.

Before we jump into this big biological answer for you, I want to check that you guys are

subscribed to our channel and if you are, then have you clicked that notification bell?

If you haven't, click that big beautiful bell and make sure you're the first to hear

answers to our Life's Biggest Questions.

Hearts keep humans and most animals alive.

We breathe in Oxygen which is diffused into our blood from cells in our body.

The heart works by pumping oxygenated blood around the body, keeping it alive and healthy.

It also works to pump away all of the carbon dioxide produced when we breathe in too, pumping

deoxygenated air to the lungs, which is defused in the walls of the alveoli, ready to be exhaled.

Our heart is crucial control centre in the natural machine that is our body.

Without it, the body would have no way of transporting blood and oxygen, which would

mean organs, including the brain, would die and our blood would congeal.

The longest we can survive without the heart pumping blood around the body is approximately

4 minutes.

This is the amount of time the brain can go without oxygen before brain cells start dying.

This is why some people revived after 4 minutes live, but suffer severe brain damage.

In short, we can live without a heart for little under 5 minutes….

UNLESS….

Well… that is the big unless ladies and gentlemen, because once again science makes

the impossible possible…there is a small handful of people who have lived without heart.

The concept of artificial hearts has been discussed and experimented on by scientists

since 1937 when an artificial heart was inserted into a dog by Soviet scientists.

More recently, Doctors started testing a continuous flow device in a number of cows.

This was a heart like contraption that used blades to control and circulate blood flow.

In 2011, this device was installed into a very ill patient, Craig Lewis, who was suffering

with a heart condition and was told he was about to die.

When the Continuous Flow Device was installed into 55 year old Lewis, he became the world's

first heartless man.

When Doctors listened to his chest he had no pulse, but blood was being pumped around

his body allowing him to live.

Sadly, he did die after 5 weeks, but this was as a result of underlying health issues.

A bigger success story, while waiting for a heart transplant, fitness model Andrew Jones,

had an artificial heart and pacemaker in a backpack.

Not only was he living without a heart, he managed to maintain a fit body, which is incredible.

He once said "I'm pretty much the best looking zombie you'll ever see."

Similarly, a 25 year old American called Stan Larkin lived with an artificial heart for

almost 2 years before receiving a heart.

There are some species that don't need hearts.

Jellyfish, for example, don't have hearts, nor do sponges, or flatworms.

These animals have other circulatory systems, but as humans do not work in this way.

So, in answer to our question, humans can indeed live without hearts so long as they

have a heart like device that is able to pump blood in a way that a heart would do however

at the moment these seem only temporary fixes for people awaiting transplants.

Although, as with all medical advancements, who knows what the future of science may hold.

Perhaps one day we will create an artificial heart good enough to allow us to live without

a real one.

So, that is one big question answered for you.

Things About Mean Girls You Only Notice As An Adult - Duration: 4:15.

Love it or hate it, Mean Girls is a pop culture icon.

But there's a huge difference between watching a movie about high school when you're in high

school, and watching it as an adult.

While you may now be able to fully appreciate the satire, some things aren't quite as funny.

Speaking Swahili

For someone who grew up in Africa, Cady seems absurdly out of touch.

"Jambo!"

"What?"

Her assumption that the black students speak Swahili is the sort of casual racism you'd

expect from someone who doesn't know there are an estimated 1,500 to 2,000 languages

spoken in all the countries of Africa.

Nevermind the fact that Cady automatically assumes the black students are, in fact, African

in the first place.

Racial segregation

There's a lot of racial diversity at Cady's high school.

"Here, this map is gonna be your guide to North Shore."

But did you notice that many of the cliques are divided by race?

Yes, it's a satire, but it's pretty disturbing — and a little too cartoonish — to see

Asian-American students and African-American students in the film only hanging out with

people of the same skin color.

Trendy on top

It's a pretty well-established fact that Cady has zero fashion sense.

"You can't wear a tank top two days in a row.

You can only wear your hair in a ponytail once a week.

So I guess you picked today."

Yet somehow, when she puts her hair down, we see that it's cut in trendy layers.

The hairstyle Cady is rocking was one of the most trendy haircuts of the 2000's.

Ms. Norbury's story

Not only has Ms. Norbury just gone through a divorce, but she's also working two other

jobs in addition to full-time teaching.

"Oh my God that's Ms. Norbury."

"I love seeing teachers outside of school.

It's like seeing a dog walk on its hind legs."

In real life, many teachers are underpaid and teacher salaries are slipping.

With wages significantly lower than that of other college-educated professionals, more

and more people are opting for more lucrative career paths which is leading to a shortage

of teachers.

Those who do join the education workforce often have to pick up a second job just to

make ends meet.

Kevin vs. the Plastics

Yeah, Kevin's rap was a little risque.

"Ugh, Kevin G"

But it's nowhere near as bad as the dance routine the Plastics performed.

Kevin's suggestive lyrics got him kicked off the stage, while the Plastics were allowed

to complete their entire routine.

In 2016, BuzzFeed gave Rajiv Surendra another chance to perform Kevin's rap — without

a shirt.

Needless to say, fans ate it up.

Piano skills

We know that Ms. Norbury's second job is working as a bartender, and judging by her piano skills,

a music-related job is likely her third.

When Gretchen kicks over the CD player with the Plastics dance music on it, Cady starts

singing and Ms. Norbury immediately jumps in on the piano with a flawless, unrehearsed

rendition of "Jingle Bell Rock."

Bad at math

The fact that Cady's crush and Regina's boyfriend, Aaron Samuels, is bad at math is a significant

plot point in the movie.

In order to convince him to tutor her, Cady pretends to be even worse at math, leading

to her calculus grade totally dropping.

"How'd ya do?"

"Not so good.

Y'know I think I need a tutor."

But as math-savvy adults will notice, it's pretty clear that Aaron isn't just bad at

math — he's awful, especially for his grade, and he probably needs a tutor himself!

Handwriting on the wall

Regina implicates Cady, Gretchen, and Karen in the burn book scandal by writing terrible

things about herself in it so that the only people not mentioned are the other Plastics.

The trio gets into trouble after copies of the burn book are distributed throughout the

school, and are then accused of writing it, even though they insist Regina is the culprit.

But somehow, despite the fact that the book is completely written by hand, it never occurs

to anyone to check the handwriting in it against Regina's.

Probable cause

After the burn book is revealed, Ms. Norbury is investigated by the police because of an

accusation that she is a drug pusher.

"I gotta say, watching the police search my house really was the cherry on top of a fantastic

year."

But it's highly unlikely that the police would have been able to obtain a search warrant

for her house, based on a rumor started by high school girls.

By law, there must be probable cause in order to issue a warrant and the burn book is hardly

a credible source.

Are Standing Desks Overrated? - My 1 Year Experience - Duration: 5:39.

I've been using standing desks for well over a year now.

But do I think they are overrated?

In my opinion some standing desk solutions aren't really worth it.

The health benefits of standing is highly debated and probably not that beneficial.

And I strongly believe a good office chair is a better investment for your money.

But considering all of that, I would still buy another standing desk if I had to make

the decision all over again.

Hi I'm David these are of thoughts and experiences with Standing Desks

I really enjoy switching from sitting to standing whenever I'm feeling sore from sitting for

too long.

Even in the most expensive and fanciest of chairs, I'll still get a little antsy or

fidgety.

So switching between sitting and standing helps alleviates that problem for me.

Sure if you don't have a standing desk, just stretching or taking a water break regularly

is going to be good enough.

But if I'm deep in some work, standing at my desk lets me stretch my legs and pace around

and still keep focused on my work.

Even when I'm not working having a standing desk at home makes it a lot more convenient

to jump on and off the computer to change a song, google something or respond to some

email that can sporadically occur throughout the day.

But I'll be honest, I still probably still sit for about 80% of my day.

Since sitting at my desk is just as important as standing at my desk, I really don't like

permanent standing desks or any manual standing desks that require a lot of effort or time

to adjust.

Sure you could use a high chair with a permanent standing desk but getting good ergonomics

out of a high chair can be quite challenging.

Manual crank standing desks do allow you to switch between sitting and standing and are

usually quite a bit cheaper.

But I personally found the process of cranking, slow and a burden that resulted in me being

lazy and not bothering to switch as much.

Tabletop risers are also an option, and are probably the only solution for those stuck

in cubicals where you can't switch out to a new desk.

But it's definitely not my preferred option as they are bit clunky, take up lot of desk

real estate, and don't really allow you to do anything else standing up other than

use your keyboard and mouse.

So I think for most people, if you want to get a standing desk you should probably save

up for a fully electric motorized standing desk.

The good thing though is that budget electric standing desks are pretty widely available

these days.

Though there are some key things that I'd look out for before you go and just buy the

cheapest thing available in the market.

Like memory buttons.

Definitely get a desk with a memory button if you can.

One click to stand, One click to sit.

Simple, no fuss.

And completely worth it.

2 memory buttons is good enough for a single user but more is better especially if have

multiple people using the same desk and need different heights.

Next, check height range for the desk.

I guess I'm on the shorter side at 5'7, so the standing height has never really been

a problem for me, but I find the minimum heights, usually around 27 inches, is often are too

tall for me, so I end up needing to use a foot rest with a desk at this minimum height.

But if I had to look for one again I'd try to find one that can go a little lower to

accommodate my shorter legs.

Checking the stability of the desk is a little more challenging.

I think at the highest height most electric desks will have some sway to them if you try

to shake them.

But honestly I've never really have an issue with stability while just typing or using

a mouse on a computer.

If you're sensitive to shaking, much taller than I am, or just doing more vigorous tasks

that require the desk to be super stable.

You could look for a desk that has a crossbar underneath but I tend to hit those with my

knees or legs.

Or you could find a four legged version of a standing desk but those can get pretty pricey.

So I think for most people you really won't notice issues with stability on anything half

decent during regular use.

Standing on your feet will be tiring especially if you're not used to it.

Even standing on carpet gets pretty tiring on the soles of my feet.

Most people will recommend getting an anti-fatigue mat which is a good idea.

But you will need to constantly move it in and out of place when switching from sitting

to standing, which is pretty annoying for me, so I personally don't use one.

Instead I'll just use some supportive sandals or shoes when standing and while I could probably

stand longer if I also had an anti-fatigue mat.

I'm fine just sitting back down when my feet and legs are feeling a little tired.

Next let's talk about noise.

Using a standing desk at home for personal use, noise for the motors really isn't an

issue for me unless someone happens to be sleeping while I'm working.

At the office on the otherhand, in open concept, and a sea of employees raising and lowering

their desks throughout the day.

I'll probably feel a little different about the noise.

Maybe I would get used to it but I can imagine myself going a bit crazy hearing a bunch of

noisy desks moving up and down all day long.

And finally the tabletop.

A lot of companies will sell their motorized legs and tabletops separately.

So if you find the tabletops ridiculously expensive or just not in the color you want,

buying the legs on their own and then grabbing a tabletop from IKEA is my preferred option.

The IKEA Gerton is a really nice option: solid wood, good sized, and fairly affordable at

only $90.

Or IKEA Kitchen Countertops can also work really well and are available in pretty much

any color and design you would want.

Considering all of this, for me at least the standing desk wasn't a fad that I eventually

got bored with, and I still very much continue to switch between sitting and standing regularly.

While I could go back to a regular sitting desk, and I'd definitely recommend investing

in a good chair first if you don't already have one.

If I had to make the decision today I'd still definitely spend the extra cash to get

another electric standing desk all over again.

But hope you guys enjoyed this one.

You know what to do.

And I'll see you in the next video.

Die Hanffabrik in Brandenburg | sens in.motion - Duration: 2:14.

The plant can grow up to 3-4 meters.

It has one of the strongest fibers in nature.

That's why we have that big machine, which is only built to mow hemp.

Basically all farmers are free to plant hemp.

You just have to register it. It's still cannabis sativa, but the strains are different.

Here we have strains that have less than .2% THC

In the end of July, when the most THC will be present in the plant we have to make a "bloom report".

After three weeks you get notified by the Federal Institute for Agriculture and Food if you're free to harvest or not.

Our production is pretty much only about conditioning fibre.

Wood and fibre are seperated with a lot of force.

Our main product, the darning wool is a great insulating material which you can build into your flat or your roof without any risk to your health.

You don't need a mask or gloves for protection and it has a life span of over 100 years.

When I studied biology I discoverered my enthusiasm for hemp, which is a sourse for a great number of products. It excited me so much, that I found a task to give my life to.
