It is a well accepted and scientifically proven fact that how we feel mentally and emotionally affects how we act, look and feel physically. Our thoughts and emotions affect how our bodies feel, our facial expressions, and how we act and move. We can all easily identify someone who is angry, or depressed, or happy, by their face, their body language and their overall demeanour.However, not so well known is the fact that this works both ways. We can actually change how we feel by changing the way.
