#Biphasic sleep, as opposed to western monophasic sleep after the light bulb was invented. My biased anecdotal evidence, gives me superpowers when solving complex engineering tasks at work. Physical recovery from exercise seems to be far quicker too. Not even sore after a long bicycle ride. And I'm in my late 50's.

I believe it is not compatible with the timeframe of the enforced western daily grind and may be why it is not promoted.

Stacked with a cup of coffee and this is serious business. I believe people take illegal and prescription drugs for this level of performance. Side effects of good sleep is chill and confident muscle memory. Performance at work over the years has been the next level, so I shall continue this path 😸
