Anybody know about palm reading?

It is common to have very different looking lines on both palms, so fret not. Personally, I don't use the notion of 'dominant hand' because both palms represent half of your whole individuality each and are equally important. Of course, this differs from palmist to palmist.

I would view the right hand as the 'outer world', the face you show to your external surroundings, to people you come into contact with on a social basis like your bosses, co-workers etc. This is more like a facade and can be compared to the Ascendant/Rising sign used in astrology.

The left hand would mean the 'inner world' which reveals the true individuality of a person, through interactions with those he/she is intimate with - spouses, family, partners etc.

Not all life lines are curved. When they go upwards, it represents a highly independent nature which is not tied to the family emotionally nor does the person take family influences into consideration when making major decisions in life.
