Some people live their lives by the motto "no risk - no fun!" and relish risk-taking. Others are clearly more cautious and focus primarily on safety when investing and for other business activities. Scientists have studied the attitudes towards risk in a group of 56 subjects. They found that in people who preferred safety, certain regions of the brain show a higher level of activation when they are confronted with quite unforeseeable situations.  In addition, they do not distinguish as clearly as risk takers whether a situation is more or less risky than expected.
