Thank you for pointing out the negative effects of drinking caffeine all the time. Too many educational channels lately have been all "coffee is wonderful for all of these reasons and you should drink it all the time!" but then forget to add in that if you /do/ drink it all the time you don't get those nice extra wakefulness and energy effects because your body has adjusted to its presence and the caffeine just brings you back to normal instead of boosting you a bit. Again, thank you for that bit.

You're alright, I like you, you can carry on doing these videos.

I've had caffeine withdrawl. When I used to drink sweet tea daily, it would only take about two days without it and I would get headaches so bad, I'd have to go to bed. Aspirin didn't help. I stopped daily sweet tea in an effort to reduce sugar consumption. I still have coffee daily though. A perfect cup is still a special experience and enhances certain food flavors so well. It's great with cinnamon toast and apple pie of course. Oh, toasted biscuit with apple jelly. Try columbian with that. MMMMMMMM.

Spectacular! More informational videos about drugs need to be like this and not treat us like idiots. This pleased the drug geek in me.

I never got addicted to caffeine, I like it but for no reason I change my taste very quickly, less than a month and between many drinks and foods.

@AristotelisMitsiou 9 лет назад

8 years ago when i was a student i was drinking 3-8 italian coffee espresso a day. Now, im immune to caffeine and i can just go back to sleep after drinking one. Also it gave me stomach cramps so i dont drink this beverage for 3 years now.

@hjfrancisco 9 лет назад

I drink a cup of coffee maybe 1 to 2 times.. a year. I always hated the after taste of coffee. But it is a quick solution for to staying awake when I absolutely have to.

@MarinusMakesStuff 9 лет назад

Good item, those guys in the background are quite the cliche though. What company was it recorded at? Hipster Coffee Inc?

@irradiatedbadger 9 лет назад

They timed this to be released just as I was waking up and sipping my espresso ;)

Here in Italy is launch time, so after a pasta a good espresso is needed

I really can’t see caffeine as addictive. I have a coffee only when extremely tired, about 6 times in a year. There is never an urge to come back to it. It is never on my mind. Just a few days in a row when I use it hoping it will help (it never does) and then back to water/orange juice. There is no inner tug back to it. I really don’t understand people who A: Feel the effects of coffee or B: Need it.

@aaronmorein400 8 лет назад

What about dopamine? I keep hearing conflicting statements on how, if at all, caffeine effects it.

@YodaOnDMT 9 лет назад

I can't stand coffee. I prefer tea. But... Is there a difference? Coffee just makes me feel wired, has a horrible comedown and upsets my stomach where a nice cuppa in the morning gives me a relaxing, slow burning energy that you don't notice wearing off.

@bulman07 9 лет назад

I don't like hot drinks... Coke/Pepsi, I guess, but that's not very often now Don't like straight dark chocolate either No caffeine dependence for me :)

Wait what. Are they seeds until they become roasted and Then they become beans? Im confused. You heard all the time that you roast the beans..

@RuudJH 9 лет назад

Coffee doesn't keep you awake. It keeps you agitated. You're so wound up you can't get your rest. I recently quit coffee, and I can keep awake just as easily.

@MrGarycharters 9 лет назад

Coffee keeps me regular.

@queenform 9 лет назад

really? i drink coffee everyday, maybe once per week, maybe non at all, i've gone completely coffee free for months at once, no cravings, no headache, nothing at all maybe i've built up a tolerance or completely immune to it?

@DamKaKaDaNi 9 лет назад

Best thing to do with coffee is to never start ^^

@Gkkiux 9 лет назад

DamKaKaDaNi I have no idea how people can drink it. It tastes awful

@MatejSunavec 9 лет назад

Gkkiux not, when you put sugar in it

@DamKaKaDaNi 9 лет назад

In my opinion the only thing you should be adicted too is water and food.

@davebirney 9 лет назад

DamKaKaDaNi ive found air to be very beneficial as well. always take a few breaths first thing in the morning

@DarkPock 9 лет назад

No, I wasn't craving coffee. But I wanna know, Why it doesn't wake me up? I am sleepy and with fast pulse when I drink cofeee.

@Nix6p 9 лет назад

Coffee's never had any effect on me. I like the taste, but I never "crave" it and I don't feel any buzz when I drink it.

@KrzysztofKotarba 9 лет назад

I like coffee... I'm drinking one right now but do yourself a favor and buy coffee machine with grinder. It makes huge difference. It's so damn tasty :]

@sandwich2473 9 лет назад

I'm one of those 90% who aren't addicted. I rarely drink tea, coffe, energy juice and I rarely eat chocolate or anything else that isn't sandwiches, pizza, fruit, vegetables or chrisps.

@SenpaiTorpidDOW 9 лет назад

Sandwich247 He didn't say 90% are addicted. He said 90% use it for something. I do rarely eat chocolate, but I do eat chocolate, so I use caffeine. Also I seldom drink coke, which has caffeine in it too.

@pavelow67 7 лет назад

Can anyone explain why i get diarrhea after drinking coffee?

@victorengland899 9 лет назад

I am addicted to caffeine, but not from coffee. I drink a lot of diet cola drinks (preferably Diet Pepsi) and it's a known fact that there is a lot of caffeine in these drinks. As regular cola uses caramel to make it black and caramel is not a diet thing, diet cola drinks use coffee instead. I do like coffee sometimes but only if I'm in Italy. Coffee outside Italy tastes like shit and is often way too hot, impossible to drink.

took me 5 minutes to realize that's a green screen

@ckaiser524 9 лет назад

Cool video but, why would you use a green screen and then still use those annoying sounds?

@GregFoot 9 лет назад

This one was shot on location in the coffee roastery. Downside: the noise. Upside: the smell!

@caleblimb3275 8 лет назад

So basically, coffee is good because it's not as bad of a drug for you as alcohol.

@mikevlek 8 лет назад

That doesnt make it good

@kelticsage 9 лет назад

I don't believe the 45 minute peak, I can see through walls within a few seconds of my first sip. Seems more like it fades away in 45 minutes

@johanne7 9 лет назад

***** Then you probably built up a tolerance to caffeine.

@kelticsage 9 лет назад

johanne7 True, I get a migraine from hell after a day or so without it

@jimm60701 9 лет назад

johanne7 a tolerance? i think its quite the opposite, if he can 'see through walls within a few seconds' he's clearly be VERY affected by the coffee. He's just metabolising it very quickly, a lot quicker than someone probably should but im no doctor so what do i know.

@kakaisclass 9 лет назад

***** thats probably due to your metabolic rate.

wenisinchina They cheated by commenting on their own video. Let's say you got first.

@Prairielander 9 лет назад

I never understood why people go nuts over coffee. But I guess its because they are just drug addicts. Its just a socially acceptable form of substance abuse.
