Why is it impossible for your body to not move any muscles at all?

If no muscles in your body moved, you would not remain alive. Your heart is made of cardiac muscle. It beats continuously from about 6 weeks after an egg cell is fertilized until the person dies. Heart rates vary, but on average a human heart beats 60-72 times per minute throughout the person's life. In addition to the heart itself, a group of skeletal muscles form the skeletal-muscle pump.

If no muscles in your body moved, you would not remain alive. Your heart is made of cardiac muscle. It beats continuously from about 6 weeks after an egg cell is fertilized until the person dies. Heart rates vary, but on average a human heart beats 60-72 times per minute throughout the person's life. In addition to the heart itself, a group of skeletal muscles form the skeletal-muscle pump. These small muscles help the blood return to the heart through the veins by gently squeezing the veins.


You might be able to keep from moving all of your voluntary skeletal muscles, though it is difficult to remain completely still. Your visceral muscles--the smooth muscles of your digestive tract--while generally moving material through your gut, do have times when they are not active. But you could not stay alive if no muscles at all move due to the necessity of having your heart pump blood.

What is hyperbole in the story "The Gift of the Magi" by O. Henry?

The most obvious use of hyperbole in "The Gift of the Magi" occurs when the narrator describes Della's and Jim's evaluations of their two treasures—her long, luxuriant hair and his gold watch. Had the Queen of Sheba lived in the flat across the airshaft, Della would have let her hair hang out the window some day to dry just to depreciate Her Majesty's jewels and gifts. Had King Solomon been the janitor, with all his...

How can I analyze Moon and Six Pence by Somerset Maugham?

In "Moon and Sixpence," loosely based on the life of Paul Gaugin, Maugham presents a study of the tension between the "civilized" life of 19th century Europe, and the lead character's desire to throw off the shackles of bourgeois life. Charles Strickland is a middle-aged English stockbroker with a wife and family. By abandoning his domestic life, Strickland commits what many in European society would consider a gross betrayal of one of the foundations of...

What are some literary devices in Macbeth, Act V, Scene 1?

Act V, Scene i of Macbeth certainly continues the imagery that is prevalent in the play with its phantasmagoric realm, as in this scene a succession of things are seen or imagined by Lady Macbeth. Imagery - The representation of sensory experience Lady Macbeth imagines that she sees bloody spots (visual imagery) on the stairs; she also smells blood (olfactory imagery): Here's the smell of the blood still. All the perfumes of Arabia will not...
