Hello @ajewa
Certainly you have described important aspects to consider for the general care of the organism and generate a greater yield.
However, in relation to what you say about sleep is relative, because each person has a particular cycle, in many places they say that a human being needs a minimum of 8 hours to rest, however, I need 5-6 hours for it, more than that is very difficult to sleep, and I get up very well.
There are those who need more than 8 hours, even 10, and some nap during the day.
