Skeleton muscles relay on contractions to move the bone they are attached to so it can contract and relax
I'm not sure if I understand your question correctly but we food is something that will not always be there for us but it is something that we need and we crave. Food is useful in many ways and helpful. We need love because due to lonliness many have died by commiting suicide.
Well, it depends on the context and the severity. If they are mad at you when doing it, it could be considered abuse, especially if there are marks on your body from it. If it is jokingly or sarcastic, then no. Clothes hangers and fly swatters don't seem that bad, but of course, I am not you, nor am I in your situation. You won't get much help if you have no proof, so you would have to have maybe some marks or a video or sound recording. Every police officer and social worker has different opinions though, so you could get help from one with no proof and you could not get help from one even if you have proof. I would say, think wisely about what you will do about it and balance the pros and cons before you act on it.
Hope this helps and if you have any other questions please let me know :)
