Sleep

I think sleep is giving up it's secrets.

We need 7-8 hours because it takes that long to go
through the 2 part process of
a. processing and holding in nurturing and b.
processing and excreting out waste (non nurturing.)

TWO PARTS
The first part of sleep is the deep sleep or NREM.
This is used to utilize nurturing, and to store
nurturing. (Option 3 of the four options).
The second part of sleep is the on and off again REM
sleep. This part tears down non nurturing and prepares
this waste for excretion. (Option 4 of the four
options).

LENGTH
The first part is about 2-4 hours. The 2nd part is 4-5
hours in a healthy sleep period. Though it doesn't
seem to be quite that inflexible or rigid.
