Modern chairs cause adults to lose the ability to squat
While children naturally rest in a deep squat with heels flat, most adults in chair-based cultures lose the joint mobility required for this fundamental human posture.
In many parts of Asia and Eastern Europe, resting in a deep squat is a common part of daily life. People comfortably wait for trains or eat meals with their knees fully bent and heels flat on the ground. While this position is a fundamental human movement that children perform naturally, many adults in Western cultures find it physically impossible, often falling backward or losing their balance when they attempt it.
