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. These small muscles help the blood...

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 the meaning of "juggling fiends" in Macbeth?

Macbeth is beginning to realize that the three witches have been deceiving him since he first encountered them. Like jugglers, they have kept changing their forecasts in order create confusion. This is particularly apparent when the Second Apparition they raise in Act IV,   Scene 1 tells him that no man of woman born can overcome him in hand-to-hand battle--and then Macbeth finds himself confronted by the one man he has been avoiding out of a...

This is particularly apparent when the Second Apparition they raise in Act IV,   Scene 1 tells him that no man of woman born can overcome him in hand-to-hand battle--and then Macbeth finds himself confronted by the one man he has been avoiding out of a sense of guilt, and that man tells him: Despair thy charm. And let the angel whom thou still hast serve...

In Martel's Life of Pi, how does writing a diary help Pi Patel build on his leadership skills?

At the end of chapter 73, Pi first divulges the fact that he had started a diary after about a week alone at sea. Pi claims that he wrote about "practical stuff" (208) such as what he caught for food, foreseeable problems and solutions, Richard Parker, and reflections about specific events that occurred. In a sense, Pi is the captain of his ship; therefore, he must take responsibility for himself and his crew. He can...

He can do this by writing down events, problems and solutions, and reflections to look back on when confronted with repeated problems. It can ...

Why did Tybalt attack and kill Mercutio instead of Romeo, who he had originally been targeting?

Though Tybalt's quarrel is with Romeo, he begins the momentous duel in Act 3 by fighting with and killing Mercutio instead. Tybalt ultimately attacks Mercutio because the garrulous and hot-headed character insults Tybalt and goads him into a duel to protect Romeo's honor. From the beginning of the encounter in Act 3, Scene 1, it's clear that Mercutio is itching for a fight. For instance, when Tybalt signals that he wants to talk to Mercutio...
