Astrology is something not everyone believes in, but all people like to talk about it now and again. What Zodiac Sign are you? A skeptic will often try to explain why the astrological signs are often very close to the personality of an individual. Such as if a person is born in a colder climate at a certain time of the year, this will affect their development in the critical early years.
For those who use this rationality as a skeptical debunking case; well yes with regard to astrology and Month one was born and the nurturing of the mother with the child, amount of breast feeding, closeness to stay warm, body temp in early baby development, amount of outside playing during the first years, would all change ones personality as they grew thru their body changes, learned to walk, stood up fell down, observed things and categorized and imprinted memory, so yes indeed when one was born would in fact change ones personality so there could be that aspect to the whole thing, I completely concur.
Along with the thought of Northern Latitudes amount of time outside due to cold. Thus someone in the opposite seasons like a Canadian Refugee living in AZ who brought their kids to live there who had offspring, well their offspring would be absolutely opposite from the young person first learning to walk in a Northern climate in Winter time. Good points to consider.
I am not so much into astrology, however it is interesting how well sometimes they peg stuff in someone's personality. Although so often they use general terms making it tough, as that could apply to anyone. In fact as I read other astrology signs well those also apply to what I know of my own personality, as a matter of fact they all kind of fit although a few don't and in that regard a few of my supposed attributes of my sign do not fit either, so I again concur with the skeptical view or at least their debate makes sense from a rational standpoint.
