The Body Civilization Built

I began taking yoga deadly serious in the early 70’s after seeing an old man on the street shuffling along with a walker. The image was visceral and complete, and I never forgot it. That was going to be me, unless I took steps to alter that future. Whatever I did from that point forward in terms of keeping my body functional, that moment was the driver.

It took me a long time to understand why that image worked where all my best intentions had not. The answer has to do with visceral survival fear and what civilization’s innovations do to skirt facing environmental necessity. This is what I call “short term pleasure: long term pain”. Mother Nature can’t be fooled for long.

The ancestral baseline

Ancestral humans didn’t practice yoga or lift weights. They didn’t need to. Their daily life was yoga. Squatting to cook, to rest, to work at ground level—full deep squat held for hours, not as an athletic feat but as simple living. Reaching, climbing, carrying, crawling. Every joint moved through its full range continuously because the life demanded it. Range of motion wasn’t developed. It was the given at birth and maintained by living close to wild nature.

Muscle was maintained the same way. Carrying water, building shelter, processing food, hunting, digging—these are resistance training performed for hours daily under what I’d call the survival imperative. Muscles were maintained not by discipline but by the simple fact that survival required their use.

Civilization has systematically dismantled both. The chair, the car seat, the elevated toilet, the elevator—each convenience extracts one more physical demand from daily life. The cumulative effect is a body that has been under-loaded for decades in ways no ancestral human ever experienced. Yoga and resistance training are not fitness practices. They are deliberate compensations for what the ancestral environment once provided for free.

Building back natural physicality

Range of motion and muscle respond to different biological clocks, and that difference determines the natural order of priority.

Connective tissue—tendons, ligaments, joint capsules, fascia— is most plastic from birth through roughly age 45. It remodels at any age, but the rate slows dramatically after 60 as collagen cross-linking increases and tissue stiffens. Trying to build genuine new ROM in hip flexors, hamstrings, or shoulder capsule after 60 is fighting biology in a way that the same effort at 30 is not. The window is real and progressively narrows.

The window is real and it closes. ROM built during those years and maintained through continuous practice tends to persist. ROM not built then is largely unavailable later.

Note: ROM — range of motion — refers to the full arc of movement available at a joint. A deep squat, a full overhead reach, a complete forward bend. These are examples of joints moving through their full ROM. It is maintained by use and lost by disuse.

We removed the natural demand of daily movement without understanding what we were trading away. As chapter 16 observes: Not knowing the constant, rash actions lead to ominous results. Civilization is irresistible comfort. The price we pay for this is either up front by exercise or in the last decades of life by infirmity and frailty.

Muscle operates on a more forgiving timeline. It can be built at any age with proper loading, though to what degree declines with age. The window doesn’t close the way it does for connective tissue—it narrows. This makes ROM the urgent priority in youth and muscle the more flexible one, buildable later on top of a foundation already laid.

The practical hierarchy: build ROM first, in the years when connective tissue responds. Add resistance training at any point, ideally before 60, on top of that foundation. Maintain both continuously as neither is self-sustaining without use, and in fact rapidly fall off a cliff after 70.

ROM is the foundation

The relationship between ROM and resistance training is not merely sequential—it is structural. ROM determines the range through which resistance training can deliver its stimulus. A full-depth split squat, a below-parallel press, a complete overhead stretch in a pullover—these movements deliver superior training effect precisely because the range is available to be loaded. Someone with restricted hips stops well short of the most valuable portion of the movement. Someone with tight shoulders can’t reach the position where the muscle is maximally stretched.

ROM is the container that determines how much of the resistance training stimulus is accessible. The same exercise performed by two people delivers meaningfully different stimulus depending on the range each can access. Better ROM means more of each movement is available for loading. The building can only be as useful as its foundation permits.

What counts as training

The ancestral framework clarifies something most fitness culture misses entirely. Garden work, for example, is real training, not just activity. Digging, carrying, squatting, reaching, lifting under genuine load and varied demand—these are ancestral movement patterns. The body doesn’t distinguish between the gym and the garden. It registers load, range, and duration. Opportunities for training exist throughout the day: park further away from the store and walk briskly to it; climb the stairs two at a time; do a deep squat to untie your shoe laces.

For formal disciplines, Tai Chi and yoga are age-old ways of paying for the comforts you enjoy. They reconstruct the continuous, low-load, varied movement that ancestral humans performed throughout every day—the movement baseline that civilized life removes entirely. They are closer to the ancestral norm than any structured gym session.

Resistance training, properly understood, fills the gap that even garden work and yoga don’t fully cover: the concentrated high-intensity loading that produces adaptations daily movement alone doesn’t replicate. Each has its place. None is optional if the goal is to approximate what ancestral life provided automatically.

Fear is nature’s guide

What sustains a practice for decades is not discipline or intention. New Year’s resolutions fail because they are constructed in thought. The mind sees these ideal desires and then tries to fulfill them. But thought seldom produces a genuine fear signal, and without a real entropy threat felt viscerally, there is no reliable fight response. The organism simply doesn’t engage, regardless of how logical the plan appears.

The chain of causation running underneath all of this: civilization removes necessity, removal of necessity removes the fear signal, and absence of the fear signal allows entropy to hold more sway. The body degrades not because people are lazy or undisciplined, but because the necessity that once made movement non-negotiable has been engineered away by civilization’s mandate: increase comfort and security at all costs. We’ve turned evolution on its head by adapting to comfort and security, rather than nature’s way of adapting through environmental challenges — discomfort and insecurity.

Civilization is the most effective delivery system for pleasures humanity has ever built. As Buddha warns in the Second Noble Truth: pleasures are the bait, the result is pain. The only question is whether you can learn to not take the bait so much that you fail to sense the fear signal keenly enough. Any practice that reinstates that signal honestly—yoga, resistance work, garden labor—helps us return to our original self.

The walker on that street in 1973 was a genuine entropy-threat signal, necessity felt viscerally rather than reasoned in the mind, and thus never forgotten. That is why it worked where decisions don’t. It wasn’t a plan. It was fear doing what nature designed to do.
