Poor posture can manifest in various ways, such as being stiff and rigid, slumping, or slouching. Other common indicators include hunching over, rounded shoulders, and an excessively arched back. Individuals may also exhibit a tendency to stumble or have their heads positioned forward, all of which can impact their overall body language and non-verbal communication.

It is important to approach the topic of posture with sensitivity, acknowledging that many individuals may struggle with these issues due to disabilities, injuries, health concerns, genetic factors, obesity, or unique musculoskeletal structures. The observations on poor posture are not intended to offend or criticize those who are unable to alter their posture but rather aim to promote awareness. - from "The Art of Body Language" by Susan C. Young.
