In this third of a 12 part series on horoscopes, we're going to look at the third of what are called the spring signs, Gemini the Twins.

People who are born between May 21 and June 22 are Gemini. Their element is air, their quality is Mutable, their energy is Yang, their ruler is Mercury, their color is yellow, their gem is Agate, their main anatomical parts are the hands, arms, shoulders and lungs, their keywords are mentality, communication and versatility, their Tarot suit is Swords and their Tarot Major Arcana card is The Lovers.

Some famous celebrities who are Gemini are George H. W. Bush, Marilyn Monroe, Clint Eastwood, Elizabeth Hurley, Rupert Everett, Mike Myers and Joseph Fiennes.

The twins. Split personalities would be a more accurate description. A Gemini is that. One minute he can be laughing up a storm and the next he can be ready to take a hammer to your head. It is not hard to feel that the Gemini is unstable to say the least. At one moment they can be witty, quick and flexible and the next they can be glib, sarcastic, fickle and downright devious. These are two sides of the same coin and it is way too easy for the Gemini to flip from one side to the other. It doesn't take them much. Sometimes, just a look will do it.

Because of this somewhat split personality, the Gemini will try anything. Mention a hobby that they would have never even considered, like stamp collecting and they'll be at the post office the next day to start their collection. They may be tired of it by that evening, but they'll still give it a shot. There is almost nothing they won't do. Of course this can lead to some big problems as sometimes this eagerness to get into anything and everything will land them in situations that are far from good. The Gemini can get into serious trouble in a heartbeat.

A Gemini in love is a contradiction in terms. Because of the fickle nature of the Gemini, it is very rare that a Gemini will fall in love with one person and remain faithful to that person for life. The norm for the Gemini is that they will have many relationships and almost all of them will be very casual. Getting a Gemini to commit to you and you only is a tall order. On the plus side, a Gemini can be a lot of fun to be in a relationship with because of their charm.

At the workplace, the Gemini needs many mental challenges to keep him interested on the job. Because of his fickle nature, he tends to get bored very easily. Also, something that challenged him yesterday isn't going to challenge him the next day. By that time the challenge is gone and he needs a new one. That's why the Gemini will often gravitate to fields that are very technical in nature like medical research. Looking for a cure for cancer is the ideal thing for the Gemini.
