If the mercury line begins on the mount of luna or branches from the life line it is a sign of a good business head.
People with this marking usually have their own business and are succesfull.
People whose mercury line starts on the venus mount and crosses through the life line usually work in the caring business.
In the past some people believed having a mercury line indicated poor health, but this has since proven to be wrong.
It is more an indicator of personal health.
For example tiredness may make the line stronger while relaxation may make the line disapear altogether.
