  • a daily sleep-wake cycle that lasts about 28 hours instead of 24
  • Eventually, I discovered that if I stuck to a 28-hour schedule, my body was happy; I woke up rested, went to sleep tired, and everything worked great.
  • incompatible with the rest of the world

  • I probably have is called non-24-hour sleep-wake syndrome
  • polyphasic sleep
  • can be used by anyone
  • shave 6 hours off your normal sleeping time
  • all you really need to survive and feel rested is the REM phase,
  • a tiny portion of your actual sleep phases at night. You only spend 1-2 hours in REM sleep during any given night
  • If you’ve gone 24 hours without sleep
  • your body goes instantly into REM sleep as a protection mechanism
  • train it to enter REM for short periods of time throughout the day
  • 20-minute naps rather than in one lump at night

  • With monophasic sleep, you sleep for eight hours and you get about 2 hours of good REM sleep. This is the normal schedule most people use, and it means about five hours of the night are lost to (as far as we know) unnecessary unconsciousness.

  • five methods for polyphasic sleep
  • all focus on many 20-minute naps throughout the day
  • possibly a couple hours of core sleep at night
  • The “everyman” method is just a stepped ladder acting as a guide to show how much core sleep to have for any number of naps. The amount of total sleep per day is drastically reduced for each extra nap you add.

      This sounds like me, since suffering from tinnitus.
  • If you miss a nap, the whole schedule is thrown off and you’ll feel tired for days.

Animals That Favor One Side More Successful: Discovery News - 0 views

  • suggests a brain operates like a dual processor in a computer, with each of the brain's two sides kicking into action depending on the content or context of the information.



    The findings also help to explain many prior surprising observations, such as why you should avoid approaching your boss, or any dominant primate, from the left-hand side.

  • Carrying the findings over to humans, this suggests, in part, that a right-handed person isn't more successful than a left-handed one, and vice-versa, but people who always favor a certain hand, foot or eye for certain tasks will likely perform better than those who don't exhibit obvious preferences.

Apology I accidentally copied to this group four bookmarks that were intended for another group (a sandpit). A slip of the mouse whilst working with my own bookmarks. I have removed all four.

    Thanks, it's a great article. It highlights so many hypotheses. It's a pity that so little is said about theory of music as mathematics extension. And I wonder whether the observations of its social character and nonverbal emphatic function have anything to do with the mirror neurons' activity. Another dubious statement is that rhythm is a characteristic of music, while I believe it to be a primordial sense as balance, for example. It seems to be an inherent function of organism closely related to biorhythms and cyclicity of functioning of all the organs and systems. Music just happens to have the same feature; it doesn't 'create' the rhythm and doesn't 'supply' it. If the living creatures had had no own biorhythms, they wouldn't have been able to perceive the musical rhythm. The same is with food for example, we can't digest cork, and therefore we don't perceive it as food, although it's an organic matter and can serve a source of energy. Maybe, rhythm as a sense is a clue to melomania.
