A batch of the best highlights from what Fabien's read, .
Some argue that we eat more when we are sleep-deprived because we burn extra calories when we stay awake. Sadly, this is not true. In the sleep-restriction experiments described above, there are no differences in caloric expenditure between the two conditions. Take it to the extreme by sleep-depriving an individual for twenty-four hours straight and they will only burn an extra 147 calories, relative to a twenty-four-hour period containing a full eight hours of sleep. Sleep, it turns out, is an intensely metabolically active state for brain and body alike. For this reason, theories proposing that we sleep to conserve large amounts of energy are no longer entertained.
Why We Sleep
Matthew Walker
you can see that a system must consist of three kinds of things: elements, interconnections, and a function or purpose.
Thinking in Systems
Donella H. Meadows
At any given time, when you’re walking down the streets, a very small percentage of your brain is focused on the present. The rest is planning the future or regretting the past. This keeps you from having an incredible experience. It’s keeping you from seeing the beauty in everything and for being grateful for where you are. You can literally destroy your happiness if you spend all of your time living in delusions of the future. [4]
