The influence of positive thinking on your health

Many people aren’t aware that positive thinking can help prevent illness. It also comes down to the method in which you train your brain.
It’s a psychological fact that if you say to yourself "I will stay healthy" that you’re training your brain to stay healthy.
 However, on the flip side, if you were to say "I will not get sick," your brain only hears the word sick, and in turn, you may increase your chances of coming down with a mysterious flu. Even though the goal is to not get ill, just the mere way that you say the words to yourself, can affect the outcome.
