Turns out some of your bad habits might actually be good for you.

We all have a few bad habits. However, did you know some of them could actually be good for you?

For example, biting your nails exposes you to brand new germs. This builds your immune system immensely.

Burp all the time? Turns out that can help you from having acid erosion in your stomach. When you burp you get the filling gas out of your stomach, allowing it to stay nice and tight.

Curtis will love this one: Farting. Farting is healthy because it allows the gas to escape your intestines. If there's a huge buildup it can cause damage in some instances.
