Healthy muscles matter
Did you know you have more than 600 muscles in your body? These muscles help you move, lift things, pump blood through your body, and even help you breathe.
When you think about your muscles, you probably think most about the ones you can control. These are your voluntary muscles, which means you can control their movements. They are also called skeletal muscles, because they attach to your bones and work together with your bones to help you walk, run, pick up things, play an instrument, throw a baseball, kick a soccer ball, push a lawnmower, or ride a bicycle. The muscles of your mouth and throat even help you talk!
Keeping your muscles healthy will help you to be able to walk, run, jump, lift things, play sports, and do all the other things you love to do. Exercising, getting enough rest, and eating a balanced diet will help to keep your muscles healthy for life.
Healthy muscles let you move freely and keep your body strong. They help you to enjoy playing sports, dancing, walking the dog, swimming, and other fun activities. And they help you do those other (not so fun) things that you have to do, like making the bed, vacuuming the carpet, or mowing the lawn.

As the muscle contracts, it pulls on the tendon, which moves the bone. Bones are connected to other bones by ligaments, which are like tendons and help hold your skeleton together.

People seldom feel neutral about poetry. Those who love it sometimes give the impression that it is an adequate substitute for food, shelter, and love. But it isn’t. Those who dislike poetry on principle sometimes claim, on the other hand, that poetry is only words and good for nothing. That’s not true either. When words represent and recreate genuine human feelings, as they often do in poetry, they can be very important. Poems provide, in fact, a language for feeling, and one of poetry’s most insistent merits involves its attempt to express the inexpressible. One of the joys of experiencing poetry occurs when we read a poem and want to say, “yes, that is just what it is like; I know exactly what that line means but I have never been able to express it so well.” Poetry can be the voice of our feelings even when our minds are speechless with grief or joy.
