Coffee is great for your brain, unless… 

Wow after watching your video about reading and checking your subscriber count I couldn't believe it... Your quality is amazing, you gained one sub! Glad I found your channel

It’s confusing how you only have less than 2000 subs, the quality of your videos seem so professional 😳

Some of the most well edited, aesthetically pleasing and comprehensive videos I've seen have been on your channel. I'm surprised at your lack of recognition! Keep it up though nice work sir

I always stick to one cup of coffee in the morning. Keeps my morning structured, goes great with my morning reading, and doesn’t impact my sleep.

I discovered this year that caffeine consumption was giving me acne. Not from milk or sugar, just caffeine, whether it be from coffee, tea, or soda. When I stop drinking caffeine, my acne completely clears up. If I drink it for a couple days, I get break outs. Amazing discovery.

Yes, if I drink coffee 6 (or less) hours before going to bed, it becomes significantly harder for me to fall asleep. That's why I'm really careful about when to drink it during the day.

Didn’t realise how good coffee was for you, great video!

Great video, Jack. Can't wait to see your future videos. Also, can you make a video about the mental health benefits of exercise and how being active improves our cognitive functions?

just came from your book reading habit video. it’s been 11 months and you haven’t reviewed any books. holding you accountable!!

I was 100% sure you had like 1mil subs- your quality is amazing and deserves more recognition!!

your reading video was insane and now this video makes me want to get my life together. keep making videos!!!

Your videos are amazing! Very well thought-out and interesting A random thought that had occurred to me is how music affects the brain. Sometimes I like to study while listening to music and I wonder if how that affects it. Maybe that could be an idea for a future video?

Great video and excellent reasons to continue enjoying my coffee.

Great video, mate. Keep this good work, the internet need more of it. The website is also very nice :D I instinctively ran to the end of the description section to find the references, and didn't find it, so I remembered that you do write it also, and I opened your website to reach for them. I have a suggestion that could help you to reduce unnecessary and bothering comments: you could add at the bottom of the videos something like "references on website", or do like Simon Clark's recent science videos, and show the number of the article when you cite them on the video, and put them on the description. I personally did not bother going to your website, but when you grow, and you will, people could care about how easy they want to reach the information source. Again, awesome work! o/ The internet need more science based entertaining and instructive information.

Follow-up video on nicotine and other "nootropic" mental stimulants? Side note, the cadence of your voice is great for taking in information. You are great at teaching, keep it up!

Thank you for the rich and eclectic content that you provide through your quality videos

you‘re going to get huge i believe! consistency is key…. I found you through your book video and i am amazed how great your videos are, just subscribed and currently binging your videos! great work!! :))

Your sub count might not feel like much rn but the quality will eventually attract people and I'm 100% sure that your channel will blow up soon! Great video!

I wake up 2 times per night to urinate from a prostate-driven bladder evacuation problem. I use low-light Kindle reading to quickly fall back to sleep. No caffeine after 2pm, and not drinking much water after 6. I drink carbonated mineral water. I'm 75 years old.

Hoping to see you more on the home page now that you are back

This is amazing, man. I found you, and i can not believe it you only got less than 10k subs. You are incredible! Great, great work. Soy latina, así que siéntete orgulloso de que tus videos tengan tanto alcance. Hahahah ¡Saludos!

Your editing is great and feels creative

Thats seriously such a good song

Well, that explains a lot. Sometimes I feel like coffee isn't working for me anymore. I feel tired all day, so I keep drinking it until the night, it doesn't allow me to sleep properly and I need a bigger amount of caffeine the next day.

The editing is great 👍🏻

I am glad I found this channel! Keep doing good stuff

I actually saw 890k subscriber until I watched it twice and couldn't believe. You'll have one day keep uploading💜

I love coffee so much...it taste soooo good, sad that change my sleep...when my vocation over i will start do drink again, i miss the strong taste

Great video❤️ Watching from the Dominican Republic 😌

Your channels been popping lately Jack 😍

I watched some of your videos, your channel is great and very helpful! Keep it up!

Great video, great edits, I'd suggest kind of writing a script beforehand or something cause you seem to stop for a bit on some parts, but other than that it's perfect. Surprised you have just 20k subs, good luck man!

Your channel is exactly what I have been looking for! How things (like reading books or drinking coffee, etc.) affect our brain. Gained a subscriber!

You need to make more videos! LOVE this content!!! Thank you so much!

You're amazing

I don't know better than but I think its good to have one in the mornings until 10:am, and second one until before 03:00. To take advantage of caffeine also to get quality sleep.

Great video. I have been drinking coffee for the past 42 years. I recently switched to a Nespresso machine with which I consume mostly lungo’s. Anyhoo, I have my last cup of coffee around 6 or 7 pm and it is normally a decaf. Perhaps the lower caffeine in the decaf contributes to not interrupting my ability to fall asleep.

Love from India brother

These videos are impressive in content and quality, definetely liking and subscribing, hope to see this channel grow!

Where are your book reviews? :D

Thank you for such a good information I'm a student and I wanted to know about coffee, hopefully I found this video , and guess what I'm your subsciber now 😀

Wow! I just knew you less than 10 min ago and I am already addicted to your videos and I am a subscriber! And consider sharing your channel with my Major colleague Thank you for your great work Keep going! And stay safe

your videos are so fire keep it up brother

Im drinking in the morning before i start job and around 12:00 afternoon that is all.

This is the type of videos i look for on youtube. Keep up the great work sir. I’ll subscribe.

Ur pauses after u speak are unique to ur kind of delivery... it's pretty weird but differentiating

Why you have only 2k subs 😭 you deserve way way more

What benefits does coffee retain for people that it doesnt make more awake? what causes some people to not feel more awake even when they drink coffee? Im curious because I and a sibling have never had the experience with coffee that most people have.

I love your channel. It has a great aesthetic and you have been teaching me a lot. Thank you!

Just watched your video on how reading changes your brain. You mentioned that you'd do a book review every month and you said to remind you of it if you didn't do it. It's been 11 months since the video and you haven't done any book reviews so so so get to it!! I would be very interested in book reviews although I can never pick a book up to read

Great video, i loved your explaining, the editing, overall very interesting keep it up !!

How about drinking tea?

Coffee before 2 pm - Gotcha!

Very informational and interesting for a coffee lover like me. I will watch more in your vids. >3

your videos are incredibly informative ! Thanks a lot.

Making coffee while watching this hahaha 🤣 Brilliant video!

I like coffee. I just found your channel, which I also like. New sub

Great content; you are amazing keep it up 👊

Man, what a great channel, thank you so much for your work!

I have 600mg of caffeine and 1000mg of L-Theanine as soon as I wake up about 5am. And then train at 6am and bed 7-8pm.

Really interesting and useful topic! Please, take another background music, this melody was so annoying even for 5 minutes. You need something more relaxed for people just to listen on the background, not move their attention to the music. thanks!

Good content!

Absolutely loved this video!!

Great video and well put together information! I try not to consume caffeine after 2pm as well

The bgm is so distracting

Great videos Jack, really enjoyed them.

Hey jack new sub here i luv your video brother from india 🙌♥

My case is kind of reverse, after drinking coffee I feel like sleeping

Whats about being dependant on caffeine and not getting same effects after few weeks.

I'm one of the ten percent of the population that is hypersensitive to caffeine. Is decaf beneficial?

Watching this video after drinking coffee 😀

I'm here for the book review where is it? Looking for a good book to read

It’s brown crack; I just can’t stop myself

Nothing about coffee withdrawal?

Great video! Do you think the same effects occurs with black tea? Thanks

Wait so is it the coffee or caffeine? Cuz isnt coffee really bad for your stomach?

The quality is extremely good but your videos feel awkward. Im sure itll get better as you continue making videos so keep up the good work! 👍

Everyday in the morning a cup of coffee is all what I need.

Can you make a video for mobile addiction? As I'm a student and right now there are online classes going on . They are around 4.30 hours straight 🥲 . Afterwords , I just play games and just do timepass . You won't believe daily I use mobile around 10 hours 🥺 . I want to do study but there's no pleasure in it 🥺 , but I have to study cause I have to give board exams 🥲🥲 . Please help 🥺

Monthly book review?

Caffeine in coffee vs green tea, earl grey etc? Thoughts? In terms of effects and retention? Thanks.

Yooo where the book reviews at?!

How can ı talk to you?

i cant handle the caffeine sadly

where are the book reviews??? have you not been reading???

Are the benefits of coffee necessarily related to the caffeine in it? Or are there similar benefits to drinking caffeine free coffee?

Great video you should work on your story telling and not having that big of gaps in the speech !

This editing is very similar to VOX or Johnny Harris

You booming

Jack you need to sort your life out and write those book reviews you said you would.

coffee reduces the gray matter, don't drink it and that's it.

Sort your life out and make a book review please

You're amazing
