As the Huffington Post points out, positive thinking sounds useful on the surface. After all, most of us would prefer to be positive rather than negative, but positive thinking is also a fluffy term that is easy to dismiss when faced with serious, real-world issues. However, research shows that positive thinking is about much more than wearing a smile and displaying an upbeat attitude. A study by the Yale Public School of Health suggests that having a more positive outlook on the aging process could have an effect on how one experiences it. When older adults view age as a time of wisdom, self-realization and satisfaction their positive mindset opens them up to seeing more possibilities in their own lives, and that brings with it a host of benefits, both physical and emotional.
