No stomach for market turmoil? Thank your genes

No stomach for the ups and downs of the financial market? Or maybe you lost everything in the global economic downturn? Genes important for mood and risk-taking likely played a clear role, US researchers reported on Tuesday.

They found surprisingly clear-cut links between two genes and the willingness of people to gamble with money.

The study, published in the Public Library of Science journal PLoS ONE, supports others that point to brain chemicals and their roles in financial risk-taking.
