Research shows that we not only process abstract thoughts and emotions with our brain, but we use the whole body.
Some of the studies focused on how one might lean forward, ever so slightly, when talking about the future, and hinge back, just a bit, when recalling the past. Other research watched how people perceive others, whether a warm and friendly personality or a chilly demeanor, while holding onto hot or ice coffee.
You may be able to guess what the findings concluded. Guess we should all drink more warm beverages for world peace.
