All We Ever Do

this just about covers it, I think

(input, output, body)
i- read, watch, listen   (books, mags, paper, tv, movies, websites, radio)
o-write, talk, create     (phone, computer, face to face)
b-eat, exercise, sleep

or, put another way,
eat, drink, piss, shit, wake, sleep, work, play
move yourself around, things around, and ideas around
(body, ideas, things..."bit"coin!)
see, hear, smell, taste, touch (do an "internal diagnostic"!)
breathe: inhale, exhale; suck and blow 

go
to and fro, hither and yon, here and there, out and about, there and back, up and down, right and left, forward and back (!)

all we ever do is LOGISTICS (move stuff).
punctuated by naps, prayer, meditation (mind maintenance)

a more psychological angle:
-"carrots"
happy: food, sex, entertainment, nature, laughter, money, learning/teaching, endorphins, reaching goals/achievement/success, comfort, beauty, love.
-"sticks"
unhappiness: pain, suffering, boredom, frustration, sadness, anxiety, danger, sickness, stupidity, ignorance, ugliness, poverty.
