    Sleep and energy

Being hyper-alert is very energy-intensive. In sleep we use less energy compared to when we are awake (see http://healthysleep.med.harvard.edu/healthy/matters/benefits-of-sleep/why-do-we-sleep). When I was a student (some water has gone under the bridge since… So maybe my memory is … or this simple (I like simple things) explanation is not up-to-date anymore) I heard that sleeping was the natural state of organisms, and that they are only awake to eat and to reproduce (I assume taking care of offspring should be lobbed in there too, and avoiding becoming someone's lunch), after all, passing on genes is what organisms are about…

So sleep might just be about (the recurrent theme of) energy (yet again)…
