RISK FACTORED INTO GENES
RISK-taking behaviour is in our genes, Australian and international scientists have found.
People who like taking a risk — or even just tend to speed and drink too much — may have some of the genes that researchers, including some from the University of Queensland, have linked to risk-taking behaviour.
The scientists looked across the whole genome to find those regions linked to general risk tolerance, adventurousness and risky behaviours around driving, drinking, smoking and sex.
They found 99 regions of DNA linked to our general tolerance of risk, 46 of which were also linked to at least one other risky behaviour.
They also found evidence that these areas of DNA were involved in brain regions with a role in decision making.
