One of the biggest issues for me in fitting in with normal human society is that my circadian rhythm is not nearly earth-normal.
In an ideal world – say, I wasn’t working, had no commitments – I’d sleep 3-4 times a day, for as little as 45 minutes and as much as two hours. This would be just perfect for me. And I know this to be the case as periods when I’ve not had jobs for months at a time this is the natural pattern I fall into.
Never do I feel more alert and cognitively enhanced (compared to normal) as I do on that schedule.
