True or False? Muscles are only used
when you are in motion.

Muscles pull on the joints, allowing us to move. They also help the body do such things as chewing food and then moving it through the digestive system. Even when we sit perfectly still, muscles throughout the body are constantly moving.

Muscles ca only contract and they also move your joints so this statement is true and false depending on your article or the info given to you but usually your body never fully stops moving. So if by motion you mean running/walking this statement is false but your eyes also have muscles so you might be perfectly still but you are still using muscles in you body. I would say this statement is false.

Depression is lifelong, though you can get medication to with it. the difference between sadness and depression is that sadness lasts a little bit, depression last a long time and it goes on and off. people usually get depression through experiences they have been through, or genetics.
