Pinterest Fall Wreaths Craft! - Duration: 9:40.
Hey Everybody
*burping*
Welcome to another video where I do whatever I want
And today....
I wanna get into the fall season
And that's why we are making fall wreaths
I really hate saying that word
I went to Michael's Crafts and bought all of this
Especially this squirrel, I got this squirrel, I like this squirrel
And I looked up some ideas on Pinterest and was like
I can do those, I think, sort of maybe
So that's what we're gonna do
Ready for this mess?
Let's begin
I have no idea where to start
So I saw two different ones that I want to make
This is gonna get stuck and I'm going to regret all of this
I need more space
I need a crafts station
Those are words I never thought I'd say
You know, you're gonna stay here because I'm scared the dog will get you and you're my prized possession
What's your name?
You don't know.You don't speak. you're a fake squirrel
So first we're just gonna do this wreath
That is such just a gross word to say: wreath. Wreath
We really need a name for you because you look like a raccoon squirrel
Like are those a thing? A mix between a raccoon and a squirrel?
Obviously "raccoon squirrel" was enough of a description for you guys to understand what I'm saying
Do I need like scissors?
I was not prepared for my craft
Oh no
This is just gonna be a mess. I know it. I'm accepting it.
I will have something to clean up later
Okay, now.
What is this made out of?
Can this just cut? Is this cuttable?
Or is that a wire in there?
Oh this just defeats my whole thing
That's a wire!
Come on
How does this move? Why are you moving?
Oh there it goes. Beautiful
Let's see if I can do this
Okay
Wait I don't know how they did it
Do you stick it in?
Oh is that?... Get off, I don't want you
Oh wait I do. What if I brought you up closer? Oh yes...
Okay and what if I just stuck it in?
Oh yes.
Just stick it in, ladies
Just stick it in
Oh it's breakable wire. Yessssssss
Have I discovered something
I am Christopher Columbus!
Minus the raping
And stealing of other people's land! Alright
Oh. My. Gosh. It's gorgeous!
Oh, it's coming out the back
Well now, I just have to cut off all these little flowers
oh this is going to take forever. Crafts suck! Why am I doing this?
Fall spirit, Rachel! get into the fall spirit!
This one's not breaking easy. There, did it, got it. Done.
That is so satisfying
Guys, I'm just winning. I'm winning at fall
Except this is kind of summer themed
We'll put more orange and red into it!
I'm already feeling it being too flowery
So obviously we have to add some ummm
You know...
Whatever this it
Oh no it's sliding!
Oh no it's not doing what I planned. Stay'
PERFECT!
Okay it's looking great and everything, but I found a huge flaw
From frontwards that looks great, but you know how wreaths
they hang up on a wall and sometimes you can see the side of it
This is the ugliest thing in the entire world
What are you doing? Pinterest has wronged me!
So... this is a really tough time for me
Because, while the front is going to be beautiful, the sides are not
But I think I have a solution
Ahhhh!
We're just gonna wrap some yarn around it
Is this yarn? What is this? Ribbon? This is ribbon.
I got this for another wreath
That I'm gonna do
BUt it looks like I'm just gonna have to use it here, because screw everything
Pin that down though...
Crafts are dangerous
I don't know what I'm doing. I don't know what I'm doing
I do not know what I'm doing, but I'm still doing it
This doesn't look good
I don't think I'm fixing the problem
Oh no. Oh my wreath is falling apart
You know, they made this seem a lot more durable than it actually is
This is terrible. I don't like this
My whole wreath is falling apart
I.. I... I'm aborting mission
I'm aborting the mission
Just aborting, I'm aborting the whole mission
We're just gonna have the sides be ugly because I don't want to deal with that!
Oh god
Okay
So I finished this
I got so into this that I didn't turn my camera back on for an update, I just finished it
Except, I can stick things on the side... Like I started to here
But, I have a limited amount of re... I shouldn't do that
I was just about to ruin my entire thing because I'm weird and I wanted to put this on my head
Did you wanna put your little head throuhg it?
Can I stick this on your head? Your head?
Anyway, so I have a limited amount of resources because I don't want to go back to the store
Also, it's 10:30 at night so I can't go back to the store
But I"m going to do my second wreath
And if I have leftovers, I'm gonna stick it in the side
Pinterest lied, that were like "you just need like 5 big flowers and you're done". False.
This was a lot of flowers, and they're pretty big too
Anyway, so we'll set this aside and work on my second wreath
Which is this one
Oh noooo Squirrel Raccoon fell over
Don't eat him
So this one, we start out by wrapping in ribbon
Alright this one, we're just getting some hot glue out because I don't wanna risk it
Risk it like a brisket from a food truck
I just made that up, did that work?
I know
I don't want to talk to you right now Blaze, I'm very upset
You're not even gonna ask me why?
Fine, I'll tell you
I can't find my hot glue gun
This is a very emotional time for me and you don't care
I had this whole wreath planned
I knew exactly what I wanted to do
Which was this. Just copy this
The only way I knew how to do that was with my hot glue gun
And I can't even find it
Where could it have gone?
Why did it run away from me?
Well now I just don't know what to do
Blaze? Solutions? Answers? Anything? You're worthless
I don't even remember when I used it last
It's not in it's little drawer. I was so prepared, I even bought little glue sticks for it
This! What. I don't even! I'm so confused
Well, let's figure out a different way to do this
We're gonna make it up. Fake it till you make it, kids!
Fake it. Till you make it
Yes. Yas! What even is this, I don't know
Oh no, I broke it
I'm gonna stick this here. Don't break! Do not break on me
We've stuck sticks into it
It's just a temporary hold
Till I figure this out
Oh my God I just came up with it. Oh my God I'm a genius. Oh my God I know exactly what I'm going to do
Oh my God I love this
Okay. Got these!
I don't know what these are. You know, sometimes I think we just accept things a little too easily
Like I looked at these and went, "yeah that's fall. It's in the fall section. It's fall"
WHAT ARE THEY?!
I don't even know what they are but I went "that's fall related for sure"
So the ribbon I bought, they all have these holes in it
See how you can see my face still?
I apologize
So what I'm going to do, is I'm going to wrap all the way around and then...
Stick my things in at the end
For the thing of the thing and the sticking
I got this guys. And you wrap it
And that'll be the front. I'm a little bit of a genius
Like, I'm not gonna brag about it. But at the same time, I'm not gonna lie to you
I'm pretty much a genius right now. You just wrap this around a bunch
Blaze, not everything is something for you to eat
Stop. Don't you dare touch my squirrel
Raccoon Squirrel is out of the question
You know, I think I'm am going a little bit insane. I'm okay with it
Look at this ugly one I got. Look how ugly that is. Oh that's ugly!
For the most part, the ribboning is done
Let's stick this with flowers and crap, then add a squirrel
I think she is beauty, and she is grace
So what we're gonna do is stick this squirrel on it. BUT!
Squirrel doesn't have a stick coming out of it. SOoooo!
I improvi...
I dropped the squirrel
I improvised!
I cut of sticks from other things and I'm gonna stick em in the squirrel
And now the squirrel, can stick
Oh my gosh I'm excited
Where do I want her? EH AH
I think I want her there. Alright
By Golly I've done it
She's adorable. She's hiding. Hiding in the fall!
Guys, I'm actually proud of this one.
You can still see the green through it a little bit, but hey!
There is green in fall. There is green in fall
This one I think is a succ-sess
Suck-sess
Success
That was a hard word for me to say
You are so much better than the other one
BOOP! Raccoon Squirrel
There is this one I wanna do though, but I don't think I can do it because I don't have the frickin...
I can't do this one because I don't have the hot glue
This is for to put a candle in the middle of
And I was gonna hot glue flower buds to it
Like. Like it does in this picture
Like that
But I don't have any hot glue
So this one's out. I guess I'm just gonna have to stick flowers on the side of my other wreath
Life is just really tough for me right now
I don't wanna talk about it
I had way less fake flowers than I though
I didn't get like anything done. I start like right there
And then... Nothing
But you know what? It's cute from straight on
So as long as I don't let anyone see the sides of it, I think I did a good job
I think this was a successful craft
It wasn't that difficult, I will say, my niece and nephews could probably do it
But I'm proud of myself darm it!
Darm it? Who's darm it?
Why do people do crafts?
Alright that's it for today
Oh wait, I forgot I bought this
Glad I did. Now I own it
I didn't really think about it beforehand. I was just like, "that's fall"
What do you do with it? What do people do with these?
I'm so confused

Common Mistakes Made During CRM Implementation - Duration: 2:32.
♪ [music] ♪
When a company is focused on business
outcomes, or at least believes they are, one of the big mistakes that I see
companies make, probably the most often, is the mistake of believing that once the
system is live, that you no longer have need for the core team.
You no longer have the need to have people in the business driving what happens in
CRM. This is a fast-track to ending up with no adoption or a system that you
can't use, and it happens all the time. It may not be the same group,
but you need to have a group of business users that are responsible for where the
system is going to go or you will ultimately have something that is driven
by IT and will not be successful and you certainly cannot drive business outcomes
with it.
♪ [music] ♪
So there are a couple of things to think about, especially if you're getting ready
to implement CRM, or you've already implemented. And that is around who's
driving the process. So, in many organizations what happens is you think
about CRM like Word, or PowerPoint, or another piece of software that you just
want to get installed, and in that case, IT owns that solution.
CRM is different, it has to be different. And so what you want to think about is the
business has to own it because it never ends, it's not supposed to end when you
get it installed. It is supposed to evolve and what does it evolve based on?
It evolves based on the changing needs of the business, it evolves based on new
business outcomes, it evolves based on new functionality that comes in, that may or
may not apply to our business, it evolves on what the users are asking for.
So if you separate that and now you have IT solving specific problems for groups,
but not for the whole and it's not made as a part of the entire road map,
you end up with a problem, a system that's unusable, a system where IT goes out of
their way to build things and then nobody uses them. The number of issues that
IT-driven CRM implementations have is immense and we hear it all the time.

Epic Film Room Glow Up - Duration: 5:22.
Hi everybody, I'm Amanda the G and go right ahead and judge my outfit and my lack of makeup
and this ridiculous hair, I don't really care.
I am redoing this room.
Oops.
I almost hit this (laughing).
I hate that couch.
That was given to me for free by someone who used to live above me when I lived in my old
apartment, and she got it for free from the person who used to live in my old apartment,
and then before that was probably also given for free considering it has no back and those
cushions are what's supporting it.
All of this, which is the background, is getting moved or going away.
And there's a picture up there that nobody ever sees.
Look, there's actually a picture.
This is gonna be a lot.
So, sped up and time lapsed because otherwise, it's gonna be forever.
(bright peppy music playing)
And we're done!
I have a shirt on now cause I totally had to go out and get more pillows, so I had to
run to Ikea and Target and I realized I probably shouldn't go out without a shirt on underneath
my overalls.
Here we have what is going to be the background eventually on videos.
So we've got an awesome chair, and then look at all of the stuff.
Little secret - that shelf right there totally collapsed to the ground, so that vase, it's
a good thing it has fake flowers cause it's got a hole in the back.
This beauty got broken.
She was- originally had a full base and now she's broken.
But that's okay because she's breaking to be stronger and I think she kinda looks better
broken, and it's a symbolism for me, I guess.
Right next to the thing that screams me more than anything else.
It is a typewriter with skeletons typing on it, and it's typing out the beginning of the
Raven by Poe.
The only way that could be more me is if it was either my favorite stanza from the Raven
or Annabel Lee.
'Be that word our sign of parting, fiend, I shrieked upstarting.
Leave no black plume as a token of the lie thy soul hath spoken, leave my loneliness
unbroken, quit the bust above my door.
Take thy beak from out my heart and take thy form from off my door.
Quoth the Raven, Nevermore.'
Back to the room, we have this lovely floral arrangement that I've put together, and Yarny,
and then we have see no evil skeletons.
The brand new couch slash pull out bed with a shit ton of pillows.
And the, uh, hexagon things that we made in a drunk crafting.
Clock is still on the wall, it's still at 5 PM.
Today's been a long day.
In the middle of doing all of this, I had to run to the store, I broke a couple of things,
and I had to destroy a couch.
I got stuck in a Friends moment with pivoting when I was trying to get that stupid old couch
down in the basement cause it was just gonna be a spare couch for the basement, and then
I had to literally hack it apart.
But I won!
So that's it for this video.
If you liked it, click the like button and subscribe to my channel, I make a new video
every Tuesday.
Thank you guys so much for watching.
MWAH!
Name a more iconic glow up than this room.
Go ahead.
I'll wait.
Except not really because this is pre-recorded and you're gonna write it in the comments.
but I'll read it in the comments!

Waterfalls of Gianyar - Bali Trip Agustus 2017 (Day 2) | Indonesia Landscape Photography - Duration: 11:33.
Okay, this is my third day in Bali
Previously I planned to photograph some sunrise and sunset
I've check some weather forecast app, and according to them
The weather for today will be overcast, and
I also make sure before went to bed yesterday
And yeah... For today, it will be overcast all day long
And it occur almost in every location in Bali
So, I am...
Not even bothered to wake up early to catch sunrise
And for today, I changed the plan and go to some waterfalls
So they are located around Gianyar
The waterfalls itself are quite easy to access
We don't have to trek or walk a lot to get there
We'll see
Okay, I've shoot the waterfall from a quite close distance
The terrain isn't quite easy, you have to get into the water
Uummm, now I'm trying for the second composition
I backed up a little bit
In order to get some foreground
We'll see..
So I'm back at the car park now
As you can see
Uummm..
The walking was..
Not necessarily hard
But when you're walking while bringing camera, video camera, tripod, filter, and so on
It became quite troublesome, not difficult but it was making my coordination occupied
Because I need to get into the water
Which is above the knee and...
I have to, uummm...
Try to find solid foothold
So I didn't fall off
And carrying stuff with my both hands
Really need some careful coordination. That's why I didn't shoot footage of myself taking pictures
And the process of taking pictures also became quite tricky because
The sprinkle from the waterfall tend to make the lens covered by droplets
I have to wipe the filter that attached on my lens
Also the lens element behind the filter
Yeah, the front side of the filter and the lens element
And I have to wipe this video camera as well
Which hassled me quite a lot
Let alone the foothold
Yeah, so...
So uummm...
I can't do much thing other than took some pictures
And I couldn't really talk about the camera settings etc while shooting
But I got my two decent shots
Two different composition
Uummm...
Now I'm about to go to the next waterfall named Tukad Cepung
I've never been there, just heard about it...
Just heard about it today because I googled earlier for location
Somewhere near this waterfall
So I decided to go to Tukad Cepung
It's about half an hour drive from here
We'll see...
I'am heading to Tukad Cepung
Uummm... I saw the parked vehicles, it shouldn't be crowded there
The thing is
From what I saw on Google, the waterfall area is quite narrow
So it will be really hard to take picture if the location is crowded
But so far so good
There are only few vehicles at the car park
I've been walking for 5 minutes
I can hear the sound of the waterfall from here
Compared to the waterfall before
This one is much
Less hectic
The walking is quite enjoyable
flat and quiet
And hopefully it won't be crowded there
Okay, now I'm going back after took some pictures at Tukad Cepung
If you saw me put my tripod and directly took a shot
That's a lie
I spent more than 1 hour there
One hour to find out which composition is the best
Back and forth, zooming in and out
But I spent most of the time setting my exposure
Because, ideally...
Ideally I want the exposure about 8 seconds
Besides I want the waterfall looked very smooth
I want the foreground, the flowing water looked smooth as well
But
8 seconds seems too long
Because I put the camera so close to the waterfall
So
It doesn't took very long for the lens to become wet
Lots of droplet caught by the front element of the lens
That makes the photo look terribly bad with spots
So, from that initial 8 seconds exposure
I stop down to 4 seconds
Then 2 seconds
Then 1 second, and finally 0.5 second
So 0.5 second is the final point where
Uumm...
The water droplets isn't really visible, while I can still manage to
Make the falling water looked smooth, but by that shutter speed
The foreground then became quite sharp
And if I went faster than that
Even the falling water would appear sharp
So I have to give in the foreground
With that 0.5 second exposure
Even with that shutter speed, the droplets still manage to appear
And I will spend more time on Photoshop to remove those spots one by one
Okay, uummm
That's all for today

See You!

Riot Lead member EXTREMELY negative comments towards Tyler1 -Most dedicated League of Legends FEEDER - Duration: 4:39.
Hey whats up guys, its League of Drama here with fresh news from the LOL community,

"This was on the league of legends discord, and for those of you who don't know, "
"streamers, pro players, rioters, are all verified as non-imposters."
"No matter how your opinion about Tyler1 is, a Riot Member shouldn't wish for someone's dea**"
as explained by the reddit user,
a verified Riot employee, was having a conversation on the League of Legends discord
saying extremely negative things about Tyler1.
"Free Tyler1, to make 100k plus a year, on being a d*ck in a game he didn't make"
"He looks like a damn homunculus" "Honestly, its fine,"
"he'll d**from a coke overdose, or testicular can*** from all the steroids,"
"then we'll be gucci"
"you know how much bullshit he´s caused me personally?"
"i have spent many many hours of my work day, dealing with his bullshit"
"i mean, i get it, i get the comedy of his streams, and his brand,"
"but its at the expense of a lot of other innocent people, and thats not cool"
"what kind of sociopath does that?" "he only does it for the views, and the percentage money"

"Reddit, League Players, Tyler,"
"I displayed a gross error in judgement last night and whole-heartedly apologize for my comments,"
"They were out of line, and not what any of you deserve to hear, especially from a Rioter."
"I'll be taking time away from reddit, discord, and in game chat, to reflect on how i communicate with players."
"Sorry again for the insults and the language."
a few hours after, this is what Tyler has to say about that:
"It really sucks that some people still hold a massive grudge against old T1, and refuse to acknowledge that i've changed."
"With that being said, i have no hard feelings towards the guy, shit happens."
and this is Riot official response to this situation:
"To be very clear here, what was said is NOT okay, and we take it extremely seriously."
"I'd like to apologize on behalf of Riot to both Tyler1 and the community for this."
"We will be taking action internally to address this,"
"(although it would not be appropriate to go into specifics here)."

Do Generic Medications Harm Patients? - Duration: 2:49.
A gift to Big Pharma this week as a study appearing in Circulation Cardiovascular Quality
Outcomes appears to show that the introduction of generic drugs is associated with a spike
in adverse events.
Before we get to the details of the study, a word on generics… in general.
Generics are evaluated based on documentation of bioequivalence to a brand and this has
a very technical and precise definition.
In the US and in Canada, for example, generics must show that the maximum concentration achieved
after a dose and the area under the dose curve is similar to that of the brand product.
But it is possible that the clinical effect of a generic may not be perfectly correlated
with its pharmacokinetic profile.
In that case, the introduction of a new generic may be met with adverse events among those
who switch.
This study examined what happened when three brand name drugs - all within the angiotensin
receptor blocker class – lost their patent allowing generics to be introduced to the
market.
Using administrative data encompassing all of Quebec, the researchers found that right
after the generic versions of these drugs became available, those who received the generics
had an increased risk of ER visits and hospitalizations.
Here's a representative graph looking at the introduction of valsartan.
You see a sharp uptick in adverse events the month the generic is introduced, followed
by a return closer to baseline levels.
What's happening here?
One explanation would be that a patient is switched to a generic and, due to a different
clinical effect, suffers an adverse event.
In the case of an ARB, maybe these ER visits were for hypotension or other side effects.
But I had another thought when I was reading this study.
What if what we're seeing is just the effect of new users having higher adverse event rates.
New users of the drugs who get a prescription right after the generics hit the markets are
likely to get the generic, whereas those who have been on the brand name for a while may
take some time to switch (as they may not need a refill yet) – so the spike seen right
after generic introduction may reflect the higher rate of adverse events expected in
new users of any drug compared to long-term users of those drugs.
I asked senior study author Paul Poirier about the new-user phenomenon.
He responded that "new users remained below 1% during that spike and the month after…we
do not think that the observed increase in adverse events right after generics commercialization…reflects
an acute reaction to a new ARB treatment regimen".
So not many new users, apparently, but the event rates increased from about 1% to 1.3%
in that first month – a small amount that could potentially be influenced by even a
small influx of incident users.
In any case, it's reassuring to see that in the long term, there doesn't seem to
be an increased risk associated with generic medication use.
I'll still happily switch my patients to generics, but I will also be extra-vigilant when doing
so.

Doomsday Machines - Duration: 6:52.
You won't see it coming.
But what follows has enough power to reshape the world.
Since 1945 the world hasn't fought with nuclear weapons, which means you probably
don't know–really understand–their devastating power.
Be thankful.
But understanding the reality of what they can do, the destructive potential locked within
the tinyness of atoms… is why this can never happen.
[OPEN]
The nuclear age began on July 16, 1945 in the New Mexico desert.
Three weeks after, a bomb was detonated over Hiroshima, Japan, and a second on Nagasaki
three days later.
Nearly 200,000 people were killed instantly.
Unprecedented destruction.
Over 70 years later, nuclear war remains an unimaginable concept for most of us.
But it hasn't become impossible.
[Snap] That took about a thousandth of a second.
A *billion* times longer than the processes that detonate a nuclear weapon.
These explosions reach the interior temperature of the sun, over 100 million degrees Celsius,
hot enough to vaporize anything near the hypocenterl – and that's only a blast's first effect.
Nuclear weapons work primarily in two ways that at their core both exploit the forces
binding an atom's nucleus.
Fission bombs like the weapons that struck Japan, split atoms apart.
When a nucleus rips in two, it can eject neutrons.
This emits a burst of electromagnetic energy, and scientists discovered this does bad things
to radioactive isotopes like Uranium-235.
When U-235 atoms are packed together, each split atom sends neutrons hurtling towards
their neighbors, which absorb them, and split again.
If each neutron ejected causes more than one atom to split, a chain reaction builds, and
builds until… [boom].
The mass of the fission products and the neutrons released is less than the original U-235,
and that extra matter is converted into pure energy.
Hell hath no fury like E=mc2.
The earliest nukes only fissioned 1-2% percent of their fuel, and even that was enough to
produce an explosive yield equal to 15 kilotons of TNT.
But it didn't take long for us to upgrade their effects by adding another nuclear process:
fusion.
Hydrogen bombs, or thermonuclear bombs, came later.
They're more powerful because they're really two bombs: a fission and a fusion bomb.
In the first stage, a fission chain reaction triggers an even more powerful atomic process:
fusion.
This initial energy compresses and superheats fusion fuel.
Unlike the heavy atoms used in fission, light hydrogen isotopes are violently smashed together
to form heavier clusters.
But same as fission, the change in mass from start to finish releases a catastrophic amount
of energy.
After all, it's what powers our sun.
Fission or fusion *all* of this atomic pinball happens faster than you can think.
After these first few nanoseconds, the larger effects of a nuclear explosion begin to radiate
out in waves.
Assuming you weren't reduced to your most basic elements at detonation, next you'd
experience the thermal wave.
Anything within several kilometers is instantly incinerated in the 6,000-degree heat blast,
which even farther out can cause full body, third degree burns, like being engulfed in
flames.
A fraction of a bomb's energy is released as gamma and x-rays which slam into air molecules,
ejecting a light speed electromagnetic pulse that can disable anything with circuits.
But only some of the energy from a nuclear explosion is released as light and heat.
Most of the damage comes from the blast itself, from debris, or the shock wave that radiates
outward compressing the atmosphere into a wall of pressure moving hundreds of miles
per hour.
Enough to level an entire city like a house of cards.
Hot air produced by the explosion rises – fast, the resulting vacuum sucks more air toward
the heat, and more oxygen to fuel the fireball, sending the column up and up.
The cloud that above Nagasaki stretched high enough to interact with the ozone layer.
At this height, it stops rising, and spreads out horizontally, forming the cap of the iconic
mushroom cloud.
As that cloud dissipates, radioactive particles begin to fall, blanketing nearby areas with
radioactive dust that can kill survivors and rescuers in just days due to acute radiation
poisoning.
Winds and rain can carry fallout far beyond the weapon's initial target.
WIDE In the 1980's Carl Sagan and other scientists began exploring a concept called
nuclear winter.
The idea is that multiple explosions, like in a nuclear war, would raise huge clouds
of dust and radioactive material high into Earth's atmosphere, blocking out the sun for
weeks or months.
This would lower Earth's temperature, slow the growth of plants, disrupt the food chain,
maybe even trigger another mass extinction on this Pale Blue Dot.
Depending the size of weapons and where they're used, as few as a hundred explosions could
cause major climate change.
And even a handful of small-scale weapons would likely have measurable effects on our
weather for years.
The first moments after a nuclear detonation would unleash the terrifying power of physics
on anyone and anything nearby, but in the wake of nuclear war, the outlook for our entire
species is just as dim.
The issues surrounding nuclear weapons are incredibly complex, but science has not only
let us create one of the most violent tools imaginable, it's also let us understand
what will happen if we use it.
Or if we don't.
Stay curious.
