I'd like to support your blog - I couldn't see a 'buy' link on your posts above. How will the CES peops know this is a link from your site?

I'm nearly 17 years old. Should I do this? I read previous comments and you said to a freshman in college that it's okay as long as you follow the bulletproof diet, but you told Ty that if you are still growing you should wait it out till your 23, at the time when your PFC solidifies. I also am not sure as to what is meant by my PFC solidifying although I did look it up and found that it stood for proteins, fats, and carbohydrates. I am pretty excited to try this out, but a little scared to since many other online sources say that a 17 year old like me needs nearly 7 to 10 hours of sleep in order to grow properly. Thanks. I just found this website and think it's amazing.

PFC == Pre-Frontal Cortex

Let me reason this out:
Getting less sleep = Being more productive = achieving life goals = being successful.

Here's the problem: The human brain has evolved for hundreds of thousands of years to accept 7.5 - 9 hours of sleep. That is the only way that we can function without falling asleep at the wheel. That means that you CAN produce more if you have more time, but you CAN'T produce the same quality of work . . . It simply isn't possible because you'd be assuming that the DNA your using to read this right now will suddenly mutate given a steady 4-hr sleep cycle and a To Do List of well-timed supplements.

It's the same as saying "If I practice, I can learn to go without water for 4 days... maybe even 5!". See how silly that sounds.

I hate sleep. But the only way that I can get around the loss of time while sleeping is to be twice as productive when awake. I'm not German, but I structure my day like one. I go to bed at the same time and wake up at the same time every day. Little sugar, eat healthy, plan accordingly and add skills that can reduce the time it takes you to do something. Learn things like the School of Phenomenal Memory so that you can recite a textbook from memory after 60 days. Then use that information to work on your company and streamline things faster.

Set aside time for planning and time for action, AND STICK TO THE SCHEDULE. Have a checklist and rate your skills. Get excersize and get obsessed with your craft. Know everything about your craft and anything that could stop you from reaching it.

Read 48 Laws of Power and review each law every day. Here's the most important part. Focus on creating more time for yourself by making your craft profitable enough to support yourself, you'll be working towards an extra 9 Hours available in the day!!. Then build on that to make yourself wealthy. After that you will have all the time in the world to pursue any dream you like.

But no . . . getting 3-5 hours of sleep can't be done for a Human Being so put your energy into something that CAN happen. You can achieve anything you want, but quality is just as important as quantity.

ending this little tirade with "quality is just as important as quantity is subtly self-defeating.

the human organism has evolved for however long you said to just SURVIVE. are you trying to convince people out there that when we first started as cavemen/hunter gatherers we got... 7.5-9 hours of sleep? really? in a world where there are plenty of predators and no set-in-stone ethics to protect you from your fellow man stealing your deerskin shoes... you telling me us humans got 7.5-9 hours a night?

"see how silly that sounds?"

plus it's not dna. or perhaps you mean genes. whatever you mean I just watched something on discovery science (called are you good or evil) where they gave a fantastic example of a guy who had the same exact brain activity and specific gene present, in quite a large magnitude, as murderers and/or violent psychopaths. those with those markers usually went on to become murderers, including a few people in his family.

due to his ENVIRONMENT though, that gene and that brain activity did not express in the way it does for someone with the same markers but a frightening or threatening environment.

also just saw some study that put african honey bees (killer bees I think they called them) with a more tame cousin, and even though the killer bees still had the aggressiveness in their genes, it didn't express because of the environment they grew up in.

also there was a through the wormhole episode in which they showed some scientist's work where people merely MEDITATED for 15 minutes a day and made changes on a GENETIC level regarding stress.

people like you would be the ruin of man. "well, we've been doing the same crap for millions of years, why change it?"

yea. why make a tractor when we have oxen? why a car when we have horses and buggies? toilet paper?! pfft, I have my left hand (vintage 2000's Iraq).

why notice an inefficient or at least not fully efficient pattern and seek to improve it?

and ps, dna doesn't help you read, or make me blatantly omit punctuation and capitalization. English class does.

Wise guy: I think 99% of what you typed is hot air.

99%? you're being so modest.

Sean, I like your post a lot. Can you email me if you see this preply at westbeach@inbox.ru? Thanks!

You'd be surprised what is possible. It IS common held belief that the human body cannot survive longer than 3 days without water, but that simply isn't true. In fact, I don't even know how they came to such a conclusion. I once lived on no food OR water(including no showering) for 10 days straight. I'm living proof that our modern science doesn't quite have all the answers. Let us carry on and look at every possibility with an open mind.

You aren't living proof of anything except that people lie on the Internet.

So, if Bulletproof sleep isn't safe for younger kids (such as me), and also we're poorer and can't buy these gadgets, is there anything we can do but wait it out? Is there some diluted version of this hack that we can use? It would be super awesome and helpful if there was...

You can get a zeo for $39 on Groupon! Start monitoring. Take your magnesium at night. Take an adrenal extract in the morning if you had a very late night. But most of all eat the bulletproof diet and your body will do the right things.

Have you done any comparisons between the data of Zeo and more low-level apps such as SleepCycle? I find that Sleep Cycle matches my own perception of sleep quality fairly good, and I would hate to buy a Zeo just to find that it gives me the same graph, just with an annoying headband on:)

There is only one Man who Will make you completely fulfilled, and that Man is Jesus. I promise that if you seek him and let him into your heart you will experience rest and Everlasting Joy. I pray that you will take this message to heart and experience TRUE Happiness in Jesus. God Bless. ps. Pray to Jesus about all of your problems so that he will help you like he has helped me always.

Shut. The. Fuck. Up

Preaching may be annoying, but there's no need to be rude.

The rudest thing in this particular thread is the preaching. Nobody was talking about religion. I'm all for politeness, but people that do that really need to shut the fuck up.

Cussing someone out and questioning their sexual orientation is way more rude than a random comment about Jesus that no one wants to hear.

The comment is not random: the blog is a sermon on the religion called biohacking. The fact that one reader responded with a comment about their religion is fully understandable. The error is in making the two mutually exclusive: the most productive human being is one who is optimized spiritually, emotionally, mentally, physically, and socially. As a Christian, I believe that Christ is the only One who can optimise my spiritual being, with positive effects on the other four aspects of my existence. That doesn't stop me from recognizing that there is good advice in this post about optimizing my physical and mental being so I can be the best person I was created to be.

Sermon on the religion called biohacking... you're a special kind of stupid.

To the people who responded with rudeness and profanity, I would like them to weigh if their comments are productive or destructive. Then, they should consider if being a destructive person online is related or not to being a destructive person offline. Then, since this is a blog about being more productive, consider how inappropriate are their destructive comments. At least J was trying to help!

Why is being productive or destructive so important? It could be said that cutting down rain forests are both productive and destructive.

Maybe you shouldn't pass judgement on what someone's intent was with their comments and just love thy neighbor.

Just Sayin'

"Love thy neighbor". Never has something been so often preached and ignored at the same time.

The lord is anything but rude! Have faith!

Have Faith! Believe in something that can't exist in order to validate my own belief!

God can't exist? That is a ridiculous statement.

Anything that exists can be eventually proven to exist. God has been dreamt of for millenia, and no one has ever been able to prove his existence. Therefore, he most probably not only does not exist, but also CAN NOT exist – if he could, there would be some kind of proof by now, don't you agree?

Two possible responses you could have, and ready-made rebuttals for those:

1. "God doesn't want us to know He exists for a fact (possibly because he wants us to have faith)" --> Well then he doesn't exist, for me. When He wants to make himself factually known, I'll change my position.

2. "Humankind/our souls have not evolved/matured enough to prove the existance of such a higher power". Well then he just as well doesn't exist to me. When his existence can be proven, sign me up — before that, it's just fairytale.

I am working on my own "Theory of Everything" that includes a lot of evidence of God's existence from many different sources. At this point I believe I can prove God's existence concisely, but I have at least two decades of work ahead of me.

In any case, if someone proved His existence a hundred years from now because of new technology or new evidence you would look like the idiot that you are. Unless you possess the entire sum of all knowledge that can be acquired then you should not make statements like "God can not exist."

P.S.: The world is not flat.

You're going to prove the existence of God? Sign me up for a front row seat, buddy! That's something I'd love to see someone really try to do during my lifetime.

Good luck on your mission! (You're gonna need it.)

I am not your buddy and luck does not exist.

So how's that Theory of Everything coming up, buddy? Any luck in proving God's existence yet? I'm still signed up for that front row seat! Can't wait!

Pretty well. How is your trolling coming along?

Not everything that exists can be proven to exist. Did not the far expanses of the universe exist before we discovered them? Of course. What about the things that exist that we will never discover? They still exist, and may act on us with forces we comprehend not. After weeding through the distractions in your argument, your argument is basically this: No one has proved the existence of God, therefore God cannot exist. Using your logic, I could say,"No one has proved that there is not a God. Therefore, God exists." Both arguments don't make sense. Mankind's production of information and work are the results of intelligence 100% of the time. Little wonder many observe nature and assume the existence of an intelligent designer as well.

You seem to be ignoring the word "eventually". I know we can't currently prove the existence of everything that exists, but I believe we will EVENTUALLY be able to. If or when that day comes, when we will be able to ascertain God's existence, I will be a believer, if he is proven to exist. Otherwise, I see no reason to believe in something that has currently not even a shred of factual credibility. Faith doesn't count.

Preaching is like giving birth, u must love! Love children!

This made zero sense.

I agree, his preaching is completely useless regarding this topic and doesn't belong here.

My cat's name is mittens

U must love the lord. For he created you!

What if he didn't? I think he didn't, because of a simple thing called not being able to create anything since you don't actually exist.

Is it possible that J may be seeing some level of desperation among the readers to fulfil their desires? quite possible. May be,because of that he wrote about Jesus for fulfillment. We didn’t understand time and space before Einstein, but it
doesn’t mean that the phenomenon was not there before. To understand the One you can't comprehend, you need to realize the Great Symmetry. Still it will be uncomprehending. The belief and judgment you’ve reflected here only validates your acquired knowledge from your environment. This blog is to develop and evolve you and bring you closer to yourself. One can choose to improve their wellbeing by prayers or by using HearthMath Sensor or Zeo or simply watching thoughts. All of them can be equally effective, isn't it? Try to see co-existences or the homogeneous facet of the world that you live, because it is the profound existence. More you cultivate the heterogeneous views; more distant you will be from yourself.

I'm a fellow Christian but I must say that this is an unnecessary post and honestly rather off putting. There are much better ways to share the love of Jesus than random, odd posts on a blog which tend create a response opposite than what you may have intended.

Just flag these trolls with their inappropriate and out-of-place comments, and ask the administrator to remove them. Getting our knickers in a twist only creates bad energy and anger. Ignoring posts like this (not commenting) is a way of reducing negative behavior (just like with any children)

His post was not negative in any way.

HAHAHAHAHAHAAHAHAHAHAHAHAHA

Or you know we'll just all kill each other over religion, since that's been the main contribution religion has had on mankind.

VERY VERY WONDERFUL ANSWER! T H A N K Y O U!

Dave,
Could you do a post about the sleep cycle app and describe what we should be looking for in the charts? I use the app almost everyday but the sleep quality % confuses me and obviously getting 5-6 hours of sleep the % will not be as high since I think the app wants you to get more sleep. For example I slept 7 hours the other night and it was around 80% and 8 1/2 hours a few nights later and it was 100%. I would really like to get less sleep and would like to analyze these graphs when I get less sleep to see if I am on the right track. Here are some examples of mine. Thank You
-David D

I looked at the Amazon reviews on the Zeo. There are over 20 negative reviews -- some of which are scathing (and very well written). The gist of the negative reviews is that it's a pretty machine that simply doesn't work. That's enough to keep me from buying it.

I check my sleep with my FitBit. It shows when I am restless or moving (sometimes if I roll over a lot) and when I get up. It has two settings: normal and sensitive which I can toggle. Absolute accuracy in this $99 is not that of a multi-million dollar sleep lab with electrodes, but is a pretty good measure for my needs.

Further, it counts my steps during the day and motivates me to walk/move more. Free website is good too. I've been using Fitbit for
2 1/2 years and I wear it 23.5/7 (I take it off my lanyard to shower <g>)
