True, Mechanical digestion begins in the mouth as the food is chewed. Chemical digestion begins in the mouth when food mixes with saliva. Saliva contains an enzyme (amylase) that begins the breakdown of carbohydrates.
When you chew, you are undergoing mechanical digestion. By the time the food reaches your stomach, it will undergo chemical digestion. Hope this helped :)
Honestly the thought that you don't want to die or you are not ready to die. We are wired to want to live and when given the opportunity to fight to live or die most would rather live than die.
