According to palmistry:
Palmistry is the art and science of self-discovery.
The health of a person is often indicated by the colour of their hands
Dead white hands often indicate a lack of circulation. Pink hands are usually a sign of good health in palmistry. Red hands may indicate high blood pressure. Blue is hands indicate a sluggish condition of the circulation of the blood supply. The normal colour of the palm should be rosy and pinkish.
One of the common questions people ask me about palmistry is what is the difference between reading the right hand to the left hand. Palmists will mostly examine your most active had which is usually the one you write with. Its this hand that shows your current and future trends. The passive hand in palmistry tends to show your childhood.
According to astrology:
Astrology is a group of systems, traditions, and beliefs which hold that the relative positions of celestial bodies and related details can provide information about personality, human affairs, and other terrestrial matters.
According to graphology:
Graphology is the study of handwriting and the connection it has to a persons behaviour.
The size of a letter is indicative of the writers self reliance.
Wide left margins are often in hand writing of proud or shy people.
No margins is indicative of a person who wants no distance between other people.
According to iridology:
Iridology is the study of the iris to diagnose disease.
Iridology is not supported by any published studies and is considered pseudoscience by most medical practitioners and eye care professionals.
Iridologists maintain that each organ has a counterpart in the eye and that you can determine the state of the organ's health by looking at a particular section of the eye.
