I’m 32 and taking running seriously for the first time in my life. I don’t remember what my 5k PB was in high school (it wasn’t anything spectacular whatsoever) but I ran a 24:34 in February which was likely my PB or close to it. Started running in meets starting in late April of this year. For training, I ran a 5k almost every day almost did almost no other kind of training (mostly because idk what I’m doing). By the time I did my third event on June 1st, I’d taken my PB down to 21:17. So I’m here to agree that you can make huge (though probably not optimal) improvements by just running your desired distance every day. I’ve had to adjust my goals for the year to where I’d now really like to see sub-20 and I think it’s entirely within my capabilities, which I wouldn’t have dreamed earlier this spring.

I'm a month or so into no coffee and just over a week into no caffeine. I don't think I'll go back

is that your real name? kingston knutsen?

How long did you spend each day or cumulative for the month?

I guarantee the study saying caffeine within 4 hours asleep doesn't affect sleep was wrong and someone paid someone to publish that. I bet you everything I own. I am 100% sure. Not 99.9999%. 100%.

not as dumb as the fake times......when running the 6.15 ...you were literally jogging

If you had not been weight training and took that up for 30 days, you would have significant results. You have convinced me that Dual N Back is not a good use of time, and for this I thank you.

did you ever reach the 5 minute mile

I think in the video you did not mention the training time per day Which is also an important factor of an experiment

Did you die?

What happened to your channel?

Super excited! Aquarius stepping into my North Node in Leo 🎉

I tried Dual N-back a number of years ago (around 2013), and I'm planning to start using it again which is how I came across your video. At my height of using it, I noticed a significant improvement in my ability to focus and my attention span. It made my interactions in conversations, work, and even watching movies more immersive, meaningful, and effortless. It actually improved my sense of happiness, because I felt more engaged in life, and almost everything felt easier. I really don't know why I stopped - I think like any routine that requires dedication, other distractions got in the way, and I'd miss one day, then more, then stopped all together. After watching your video, it got me excited to use it again, although I could tell that I'm "out of shape" as even considering the three-back felt a bit like brain overload. At my best, I was regularly doing seven-backs and eight-backs, and the occasional nine-back. Looking forward to getting back into it.

"Trying to get to the next thing" < a real syndrome.

Love the video. Very encouraging. I'm almost caffeine free. Just one tea in the morning. But really, I want to go all the way. Thank you for this video.

I too would never have a second cup ever again.

Thank you so much for your video. I was off coffee for a couple months and went back for a month. My anxiety is back and I can't meditate anymore! Day 2 and hard again, even after this short term back on it. I am feeling calm and gentle and willing to go through the hardships to get to peace again.

If you're trying to cut coffee due to health problems, try cutting back on coffee by mixing in some un-caffeinated Teeccino, over time you can wean yourself down to no coffee at all!

I'm on day 40. I look back and I'm thinking wow,poor decisions,poor sleep etc. Everyday I feel a bit better, I was drinking 4 lattes a day,sometimes 5,works out at about £220 a month. It's a clever buisness statagery, open a shop,sell drinks that are overpriced,give it a nice name,coloured cup etc😊,people will keep coming back until they realize they have to quit😊

In visual memory i have 12 points,in number memory 9 and in verbal memory i have 133 points

In the word game, read the words out loud, it makes it much easier

Why did you stop posting about this challenge?

Why this music???

Link for the best n-back software/program?

0:54 2nd step is the first layer corners, not edges.

I’ve been using it only a week and noticed I’m thinking faster in my sales job

Now when we are talking about science, we need to bear in mind the paper published might just have been bought by money. Out of all the people I know who've quit coffee, it definitely impacted their sleep quality big time, most of them didn't realise it until they quit. Always trust your own experience, not some potential fake research that permeate the world right now. It's a sick world we live in.

I quit for two weeks, and felt the edge come off. Then I drank one cup and it brought it right back. No more coffee for me

All this has happened to me as well, exactly in the same sequence but unfortunately there is not enough research to prove our point.

i experienced similar anxiety attack following drinking coffee, Is is not easy to stop caffeine but it is possible and certainly worth it.

Coffee is just like cigarettes

What if you stayed at level 4 or 5 using manual mode until you can consistently score close to 100%?

R u still off caffeine

you can gain a tolerance to anything your exposed to long term

caffeine is so popular globally because it is very easy for you to develop a dependancy on it

I consumed roughly 450 miligrams of coffee a day and quit cold turkey a week ago. The first 3 days I was very tired all day long. A week later though I feel amazing. I no longer crash in the afternoon during the last hour or two of work and my energy lasts until bed time. I'm more focused because my mind isn't rushing, this is invaluable because I legit listen to educational podcasts during the work day and now I feel like I actually learn something and can actually "listen" to them, Regular bowel movements, and sleep feels better(I always stopped using caffeine 10-12 hours before bed so it never affected it much) but I do wake up and im ready to go instead of waiting to dtink my coffee and that being what makes me "ready to go"

I drastically cut back on coffee, but at the same time I started to take evening walks right before going to sleep (in a safe neighborhood). I would start my routine, check my bed, brush my teeth, ;ower the thermostat etc. and then go for a walk. And at arriving home I went to bed as quick as possible. The result was that I slept better and woke up much better the next morning, more energized but calmer and happier at the same time.

I don’t drink coffee. Lol shit makes me piss like crazy

That Florida study is a bunch of crap. You need to do better research.

I gave it up around 2-3 weeks ago. This week I noticed I’m facing a very lethargic response in my body. The other day I got into bed around 6pm and stayed in bed til 10/11am the next day. And STILL feeling tired. Previous week I felt great/ambitious. Can’t wait for this wave to be over, I’m ready to not rely on coffee ever again,

I agree and love your video but I don't get why the author of the book said he drinks coffee every morning in his interview..it doesn't make much sense 😅

Niiiiice

I had panic and anxiety attacks,gut inflammation nerve damage but as I quit everything gone . I think some are not designed to consume stimulators like coffe,nicotine and sugar etc.

Suggestion: don''t use any background music.

One big thing you didn't pick up on is in the study around 5:23 it is measuring sleep duration and efficiency, NOT quality of sleep. Quality is defined as how successful you are at moving between, and having adequate time in, the different stages of sleep. Caffeine causes you to be kicked out of deep NREM sleep and REM sleep which has serious repurcussions on short and long-term health. Read Matt Walkers 'Why We Sleep' and Caffeine Blues for more.
