How to calculate the age of a person using palmistry
Choose the correct hand.
Often times, a palm reader will rely on both hands to give a more accurate reading. However, some palmists prefer to use one primary hand, and which hand is chosen will depend on both the age and gender of the person being read.

Pick from:
- Men who are under the age of 30 should offer the left palm as the primary hand. Men over 30 years of age should use the right palm as the primary hand..
- Both hands may have the same number of fingers and smaller palm which is optimal for the individual. Evaluate how many fingers you've got..
- Both hands are required for the study to be successful. For children, chose the dominant hand and the vice versa..
- Choose whichever hand is most commonly used and then choose whichever one you like the most. Use your ring finger to control the weight..
Men who are under the age of 30 should offer the left palm as the primary hand. Men over 30 years of age should use the right palm as the primary hand.
