In correct position, one should sit straight and relaxed. One should not bend in front or lean backwards [Fig.$(b)$]. The fore arms should be at the same level. The feet should rest flat on the floor. The lower leg should be erect making a right angle at the knee.
Similarly, one should stand straight and erect and not droop in front for a long time [Fig.$(c)$]. The habit should be checked from childhood when the bones are soft. Otherwise the curvature or bend of the backbone may become permanent with age as the bones gradually harden.
