How does caffeine affect us?

Coffee, Drink, Morning, Cup, Hand, Breakfast, Person

The sun is rising, the birds are singing, and traffic is starting to hum outside your window. It’s a brand new day and most of you probably won’t even crawl out of bed without a hot cup of coffee waiting in the kitchen.


Drinking coffee has not only become a daily routine for many, but also a ritual ingrained in culture and history. People gather to chat over coffee, drink it with breakfast or dessert. Some mythologies incorporate it, and many economies depend on it.

But why has coffee become such a big thing? What has made it into one of the primary substances consumed, almost on par with sugar?
Taste certainly has a part in it, but mostly coffee is favoured for its properties. In a busy world where you need to get up early and remain at your best through the day, it is irreplaceable. Coffee is considered a stimulant, keeping you awake, alert, and energetic.
How does this work exactly?

3D structure of caffeine

When the brain prepares to rest, a chemical called adenosine binds to specific receptors signaling you to feel tired, slowing down nerve impulses and gently guiding you to sleep. Caffeine has a very similar structure to adenosine, tricking the receptors into binding it instead. As caffeine intake reaches its peak, it outcompetes adenosine, preventing the brain from feeling fatigued. It also increases the heart rate and prepares the muscles for action, leaving you ready to face the day.

But for all the benefits, caffeine comes with an equal amount of drawbacks. Like any other drug, it can lead to addiction and withdrawal, even if weak, when consumption is interrupted. Some of the side effects include anxiety, insomnia, restlessness, upset stomach, irritability, and dizziness. And while coffee can alleviate headaches and migraines, habitual drinking can actually cause them.

You may feel energetic, but that feeling is a false one. Caffeine tricks the body into using up its energy reserves, which can leave you extra tired once it leaves the system.
Despite all, coffee is still the preferred morning beverage and drank reasonably in moderation can provide more good than harm.

Warehouse 13


Today we delve into one of the stereotypical government agents hunt down wacky artefacts series. In this case, Warehouse 13.
And that’s pretty much it. Simple theme, simple execution. The show is mostly carried by its wackiness, the weird objects, their effects, and the stories surrounding them. The characters, two government agents and their allies, are quite stereotypical, with one overarching trait each. True, there’s some development as the series progress, but it’s never the characters that make it watchable. Except for H. G. Wells, played by Jaime Murray, she was quite enjoyable.
The acting itself is okay, and so is the CG, nothing exceptional, just okay. The music can be annoying at times, too whimsical, or too obvious, or too annoying, but it fits so that at least is okay.
The series is formulaic, but enjoyable. Nothing too absorbing or philosophical. Just harmless, nonsensical, wacky, fun.
    So I guess that’s how I’d characterize it, wacky, give it a watch if you’re starved for a ‘government agency saves the world’ themed series and have nothing else to see.



    So what about the pilot?

    The episode opens in a museum in Washington, DC, where Agent Myka Bering, played by Joanne Kelly, is overseeing the preparation for an operation. With the comical music in the background promising whimsical, slapstick fun. None follows. For the moment.
    Meanwhile, Agent Pete Lattimer, played by Eddie McClintock, gets up from a one night fling with a bimbo who can’t figure out his job by his badge. Ah, a stuck up female Agent, and a ladies man male Agent, classic.
    Somewhere else, a random lab person is working on a creepy, round, stone mask. A ritual blood stone thingy, or so he clarifies. A minor accident occurs, he gets cut and ‘feeds’ it some blood. We know this won’t lead to anything good right from the start.   
I’m not really a fan of fragmented introductions. I suppose they work, but I prefer more connected beginnings. They make a story feel smooth, well connected, and not just patched up. At least it establishes everything fast and painless, character, situation, and stereotypes.
But moving on. The bimbo works as a server at the reception in the museum. It’s an expensive, high profile exhibition of new artefacts and the secret services are there to supervise. We see the lab attendant again, gulping in a whole glass of champagne, sweating profusely and acting creepy. The music makes sure to drive home the ominous foreshadowing, of course, along with a bloody fingerprint he leaves on the glass.
Immediately after, we’re introduced to the character conflict, Myka’s stuck up, Pete’s trying to be a playboy, perhaps I mentioned that already, and they are having a little alpha contest about who’s in charge. In other words, were this real life, he’d be fired or demoted at best.
Apparently, he gets ‘vibes’ so he knows what’s the best position for him, regardless of what was assigned. But this is a supernatural-ish show, so lets let it slide.
Another mysterious character with grey hair, grey beard, round glasses and a vintage doctor’s bag shows up, and the lab guy, stares at the mask with bloodshot eyes. Then the mysterious character starts disabling agents with a weird electric gun. Is he our bad guy? Probably not, the music didn’t cue an ominous, dramatic note when he entered, instead we get whimsical action choir.
Pete sees the mask bleed and whisks it off, shouting he’s secret service. Now, I’m not sure it works quite like that. So why isn’t anyone calling security?
Myka sees the lab attendent, the blood he lets drip behind him, and the knife thing he pulls so she removes her heels, gathers up her dress, and jumps in pursuit. On a different museum level, Pete drops the mask and it rolls right to the mysterious character who is now sprouting weird protective goggles. The mask is neutralized, the creepy lab guy is subdued, and the exhibition is saved.


And we’re about ten minutes into the story. Not bad. Quite a lot of action in quite a little time without feeling rushed. Though from here on the story stalls.
First we get the obligatory, I know what I saw, versus we need urine sample to test you for drugs. Pete is suspended because his story is too crazy, but then Myka and he are transferred under the invitation of the mysterious Mrs Frederic, played by CCH Pounder. The two bicker, he fucked up but why is she taken along as well to a government facility in the middle of nowhere, and etc.
Some witty banter here and there, but overall its all cheese. Granted, not that bad cheese, but still cheese.
So the agents are introduced to the Warehouse and its wacky watcher Artie, or the mysterious character we saw earlier, played by Saul Rubinek. His character trait is that he’s smart and wacky.

Also there’s a cow in front of the warehouse, no one knows why, not what the poor thing eats as there’s no grass, but there’s a cow.


They spent the next twenty-ish minutes messing around, exploring the warehouse, and coming to terms with the fact wacky sciency, paranormal things exist and then getting in trouble by mistreating artefacts. That’s what the series are in a nutshell. They either need to find a misbehaving artefact or they start trouble on their own by messing with one already in the warehouse.
There’s also a lot of mumbo jumbo about energy, predisposition, alignments destiny and all that nonsense. I like to swipe that under the rug and never look at it again, else I get a headache trying to figure out what it all means.


In this episode the artefacts in question are Houdini’s wallet, which falls into Myka’s purse by accident, and Lucrezia Borgia’s comb. The comb induces rage in a young man forcing him to do bad things, makes a teacher set himself on fire, and other random accidents all incited by the a woman under its influence.
Luckily, our agents find the artefacts, neutralize it with the purple stuff, that’s what it’s called in the series, dispel whatever hold it had over the woman, the man, and the audience of a play and all is good and well until the next wacky adventure.
They do get in a car accident in the process, you know for action and stuff. The wallet, by the way, causes ghosts to appear, for some reason, in this case bringing visions of Sam, an agent Myka couldn’t save. It’s a minor story line that goes on for a while.
Overall, the episode is okay, it introduces the characters, the theme, the plot, but it meanders a lot and a slower, calmer lookover by the writers could easily yield a faster, shorter episode. Or at the very least something less than an hour and a half, which is how long the pilot episode is. Some shows may need such a long start, this one I’d ascribe to sloppiness in writing.

Why does the road appear wet when it's hot?

Road, Destination, Mountains, Sky, Landscape, Direction
There’s no better time for a road trip than summer. But while they always lead us to exciting destinations, the journey itself can be quite laborious and hot. For hours, you may be stuck in a car, mindlessly looking out of the window, dozing off, or even driving. Sometimes in the heat of the day, a shimmery haze appears on the horizon as if water or even oil have been spilled all over. Yet there’s not a single cloud in the sky, and once you approach and drive past, the highway is as dry as it has been and the puddle has moved on.

Everyone who has observed asphalt in the summer has seen this phenomenon. It is called heat haze, an inferior mirage since it appears under the real object.


But how exactly does it form?
Under the sun, asphalt is much akin to a stove top, radiating heat and even capable of frying eggs if necessary. It turns the air drifting over it into a nice warm blanket that clings to the ground.
Like any optical mirages, the vision is caused by the way light travels through substances. Different media, including different atmospheric conditions, allow and bend light differently.
When it hits this border between the hot air of the asphalt and the cooler air above, the rays are refracted. What we see is the sky lying on the road because of how light is bent and redirected but our brain interprets it as water. Due to this refraction we may also see cars as if reflected in the surface underneath strengthening the illusion of water.
This phenomenon is also why we see oases and mirages in the desert.
