So to get your business-career up get infected with this parasite. It will make you take more risks. Beware it can also make you drive recklessly. Economically speaking you must take on some risk to get a reward. Taking on risk of course means you might just as well lose too, get eaten by cats. Many do. We mostly hear about those who survived, by chance, and reaped some great rewards. They are our heroes.

Totalitarian countries might infect their soldiers with this parasite on purpose. Scary.
