Mars In Aries. Here is Mars in the sign it rules. The planet will be of increased importance and a focal point of the birth chart. It gives an energy force which will need to be burned positively through daily physical work, sport, and exercise. These individuals will in some respects show certain characteristics of Aries. They will want to be out in front and way ahead of any rivals. They are also likely to put themselves first, so an element of selfishness can sometimes emerge. Accident-proneness when exercising or driving too fast, plus a vulnerability to burns and cuts is ever present, and the sex drive is considerably increased.
