What are some tips for maintaining good posture?

When sitting, keep feet on the floor, a gap between the back of the knees and the front of the seat, and shoulders relaxed with the forearms parallel to the ground, as a way to maintain posture. Slightly bend the knees when standing, and keep the feet shoulder-width apart.

When lying down, place a pillow under the head, making sure the head is not in an irregular position. Sleep in a position that keeps the back curved, and prevent back strain by avoiding sleeping on the stomach. Maintain knees at or above the hips when driving, and support the curve of the back by adjusting the seat as close to the steering wheel as safely possible for good posture.
