Finally, an environment with variability (hence randomness) does not expose us to chronic stress injury, unlike human-designed systems. If you walk on uneven, not man-made terrain, no two steps will ever be identical—compare that to the randomness-free gym machine offering the exact opposite: forcing you into endless repetitions of the very same movement. Much of modern life is preventable chronic stress injury.
Hmm heh so randomness and chaos is healthier to your mind ok but total opposite of The Power of Habit , by Charles Duhig .
