It is perhaps this very fear of things and people that in the end makes them misers with their gold.
One need never waste one's time asking a person with one of these cramped-looking thumbs to do a favour, and may God help the business man or woman who ever gets into such a person's clutches! A thumb with the nail joint supple (bending backwards or as it is also called "double jointed") indicates a character the exact opposite of that associated with the "tied in" thumb.

Possessors of such a thumb are generous, adaptable to others, extravagant, and impetuous in their actions and decisions.

They promise things quickly and are more often heard to say "Yes" than "No"; but if they have time for reflection, they very often go back on their promises.
Individuals having a "stiff-jointed" thumb, on the contrary, cannot easily adapt themselves to others.

They are distant and more reserved with strangers.

When asked to do a thing, they generally first say "No," but on reflection or when reasoned with, they often give in to the other and generally regret having done so.
