The video explores the complexity of defining good posture due to the natural curves of the spine. It highlights the importance of maintaining spinal health to prevent issues like lower back pain, which is a leading cause of disability worldwide. The spine's S-shaped curvature, including kyphotic and lordotic curves, is explained, along with how these curves change from infancy to adulthood. The video also discusses the lack of a universal standard for posture, emphasizing the benefits of regular movement and varying postures. Special considerations for wheelchair users are addressed, and common signs of bad posture, such as slouching and 'text neck,' are identified, with suggestions for improvement.
