most of modern, "civilized" life is based on arbitraries: clock time, deadlines, profit/loss ratios, etc.
outside, particularly as survival situations approach, is absolute, never arbitrary
i stopped wearing a watch years ago & i have 3 part time, flexible jobs because i have some health needs that have forced me to live in a more absolute, less arbitrary way
with the exception of a few days per month, i sleep or rest when i'm tired, i wake up when i'm done sleeping, i eat when i'm hungry & i try to arrange and re-arrange work to fit with my high and low energy/health days
the more and better i do this, the better i am able to live - i make a lot less "profit" than i did before, when i tried to adapt my body to society's arbitraries, but i crash and burn a lot less
survival is the same, only more extreme: anything that doesn't matter immediately to body temperature, energy level, hydration, etc, is extravagant: arbitrary
our society trains us to have a stimulus/response neural network for these extravagances, arbitraries - in survival situations, the more and faster we can deprogram and focus on absolutes, the better we can survive
cultures/societies/individuals without or with less programming for extravagance are at a survival advantage
