Chew gum when you’re nervous
Food is comforting, and our brains have been wired to believe that we are safe when we are eating. Chewing gum will, therefore, temporarily quiet your brain. Thus, this is an ideal method to de-stress a little before an exam, job interview, or date.
However, if you haven’t done your homework correctly, no amount of gum will be able to keep you from failing. Additionally, remove your gum before the job interview to avoid making a bad impression!
