What I would be miffed is that some answers are not answers. They are statements of very little content intellectually or word count.
There is nothing anyone can answer that I have not heard a thousand times before. I want to get someone to present a valid rebuttal. I do get valid rebuttals all the time so I know how to comapare.

Anyone?

My chiropractor is very attuned to both his and others characteristics as they relate to the elements of wood, earth, fire, metal and water. These are concepts that I've linked with Feng Sui color co-ordination in the past. Never heard of them when it comes to describing personal characteristics/pesonality traits. Can someone explain please?
