Look around you. In the office, on the train, in a coffee shop—you’ll see the same silhouette repeated over and over. A head jutting forward, shoulders slumped, and an upper back rounded into a gentle curve. This is the posture of modern humanity, a physical adaptation to a world dominated by screens. Our bodies, forged over millennia of upright, dynamic movement, are being reshaped by the glow of our devices, and the consequences go far beyond a simple ache in the neck. Our hunter-gatherer ancestors possessed a natural, powerful posture. It was a byproduct of their lifestyle—a life spent walking, climbing, carrying, and scanning the horizon. Their alignment wasn't something they worked on; it was something they lived. Today, we've lost that innate connection. We're told to "sit up straight," but the advice feels temporary and forced because our environment constantly pulls us back into a slump.
