Some bad things are not always bad. Sometimes a little bit of bad behavior becomes positive. There are some bad habits that you must understand if you are wiser than others.

 Some people chew chewing gum all the time. It is normal for someone to sit next to the chewing gum on the chewing gum.

 But several studies have shown that people who have the habit of chewing gum are usually more alert than others. They have more intelligence and more focus on any task.

 Another study says chewing gum improves the mind and helps reduce the stress hormone called cortisol.
