Hunger naturally caused by the decreased blood glucose level, so eating sugar will lessen it. But it also can be induced by an empty stomach. There is a receptor in the stomach that detect whether it is a stretch (mean that there is something inside it). Lack of stretch can cause it to send a signal that will result in hunger.Explanation:
you've most likely practised gnawing, painful feelings in your abdomen at some purpose, in the higher left aspect of your abdomen. These are usually referred to as hunger pangs. Hunger pangs, or hunger pains, are caused by sturdy contractions of the abdomen once it’s empty. This uncomfortable sensation is usually among hunger, or the will to eat.

Despite being known as “hunger” pangs, these pains don’t continuously indicate a really got to eat.

I’ve personally felt invisible all my life, especially when a friend turned out to be fake and didn’t seem to take any type of interest in what i said or any type of input i said. being invisible is a terrifying feeling to experience due to the fact you feel like no one sees you and just sees you (sorry if that doesn’t make sense). it’s like a deep emptiness that no one can fill, just you; you have to fix that emptiness by yourself and you don’t really want , or in some cases want to be invisible. i can see many invisible people when they intentionally stay away from people that can potentially hurt them in any way. also, when a person intentionally breaks off a connection so they aren’t seen by people.hope it

Das well as e and possibly b.
