So does every human bite they tongue when food so good and you hungry?

The truth according to Google:
The biggest reason why you may bite your tongue while you eat is due to coordination. There's a part of the brain known as the pons that is responsible for controlling habitual actions like biting, chewing, swallowing, and more. It's an action we don't really have to think about. We just do it.

Somewhere I read we bite our tongue as a result of an upset stomach?

They say it is someone cursing you, lol.
