Then achieve my goals.

I used to work in 3 michellin star kitchen in the UK. I know what sleep deprivation is like lol. Its not fun and certainly harmful. Still get nightmares about it 15 yrs later lol.

Thank for your time, Sir.
Japan is the country with the longest life expectancy, while they sleep the least. This is enough for me to send Mr. Walker and his research to hell.

Haha up2u. Be careful with citing very general epidemiological studies such as "Japan has long life expectancy and sleeps 5hrs 50 min a night". Correlation is not causation. Who knows maybe they d live longer if they remembered to sleep? Do you have any reason to believe this would not be the case? What about subsets of the population who do sleep sufficiently vs those who do not? Very real possibility that their longer life expectancy is not related to their sleep habits at all especially considering literally every country at least in the developed world suffers from chronic sleep deprivation. Therefore its likely they are just on even terms with everyone else but do other aspects of daily living better. 150% guaranteed their food culture is WAY WAY more developed then any of the bullshit we eat in the west. Japanese respect food more then anyone else on earth pretty much.

In either case you will have to be very careful with your stress management as well as taking care of yourself in every other aspect of your life. Sleep is where your brain and body deal heal, rejuvenate and grow after a day full of various stresses. Stress is very important to health but only intermittent stress, not chronic stress. If you sleep is anything other then the most efficient I cant see it being good even in the short term. Much more productive will be to get your physical training habits and nutrition dialed in.

Thanks Samu for link you shared. But i believe we can always do better. I'm not doin' it to increase my wealth or capital, i just want to increase my time to do things i like and live on this earth as long as possible.

Well missing sleep and you are going backwards towards this goal. Idk how else to say it. Chronic sleep deprivation kills you. You body and brain do not get sufficient time to fully recover from the waking day. Being awake is literally low level brain damage due to the metabolic and chemical processes that happen in your brain. Unlike your muscles your brain does not flush out the waste while awake and you must be asleep for this to happen. Therefore you get a build up of metabolic waste in your brain. This is likely a large reason why mental degenerative disease are highly correlated with lack of sleep among other things.

We are the only animal on earth that have this crazy idea that missing sleep is a good idea. Every other animal will sleep the amount they need to all the time. The only small exceptions are some birds who migrate, whales who are nurturing calf. Even then most will find a way to make sleep happen in one way or the other. Birds and sea mammals can sleep with half their brain at a time for example however if given the chance birds go into a full sleep which enables deep REM sleep.

Also writing "oh I woke up and felt not so bad today after 5.5hrs sleep" is useless. We are not very good judges of wtf is going on in our brain. Its like asking someone who is somewhat drunk are they ok to drive? Very often people over estimate their cognitive abilities and say they are ok when really they are just impaired.

In either case do what you want. If you really think that you are somehow different from every species on earth which all crave sufficient sleep then good luck.

I already respond to WM2K comment. I completely disagree with Mr.Walker. And wanna try this. At minimum i wanna sleep 5:52 (Japanese people sleep on average.)
as I continue, I will look at well-being.

Ty for suggestion! I'll do both.

I already did, i moved step forward.

By "I do not like the local design" do you mean "I do not like the responses I'm getting"? Because you can go onto as many forums as you like with this question, and you will receive exactly the same response, I assure you of that. Except for maybe insomniacs interactive, but they'll probably be more against it than we are.

I had a similar crazy idea in my head once upon a time. Looked into polyphasic sleeping and tried it out. I lasted about 36hr, felt like complete garbage and looked into it a little more and figured out its just a terrible idea.

So pretty sure if OP looks hard enough he will find a community of people who think that under sleeping is a great idea and a sign of strength. It is certainly a very well represented idea in our society atm. When I worked at the 3 Michelin star place there where literally dudes who said "idk what I would do with myself if I didnt work 16hr+ days". Gross.

I dont really get the motivation. So what live life fully by going to bed at midnight and then get up at 3am? Sounds like a recipe for spending time alone in the middle of the night while increasing your odds of chronic disease substantially at the same time. Never mind the chronic fatigue and feeling like complete balls.

Not at all sir. I'm into design. It's why i play pokerstars instead of other rooms where pools are softer. Responses i get the same, you're right and im absolutely okey with that. Maybe all post here once/twice a month.
