On a clear day the sun always casts a shadow. In fact, the brighter the light, the more vivid the corresponding silhouette. That is why any complete discussion about positive aging requires the acknowledgment that a dark side exists. And while I am certainly not a professional who understands all the implications, I do think it is important to explore how it may affect us as we age. That’s because no matter how optimistic we remain about aging, none of us knows for sure what our complete future holds. And, like with all shadow work, it’s SMART to accept its existence as well as how it can potentially affect our lives if we want to experience the days to come as an authentic and whole individual.
