The road to success in starting a business might run through a cat's litter box. A new study reports a parasite found in cat feces might make people less afraid. The parasite infects about two-billion people worldwide. Researchers at the University of Colorado tested to see if the parasite makes people less afraid of risk, for example in business. The scientists found that at entrepreneurial events, people who carried the parasite were almost twice as likely to have started their own businesses. College students who contracted the parasite were nearly one and-a-half times more likely to major in business. The study was published this week in the Proceedings of the Royal Society B.
