The body you have is a gift. It is yours to do what you will with it. You can take care of it or you can let it go to waste. The best way to take care of it is to use it, to move it. Movement is life!
Think about it. Water, that life giving element that we know and love so well, is a great example of how movement yields life. Moving water, as in a river, provides oxygen to animals and nourishment to plants. Moving water takes away trash and debris from rivers. The moving waters of a river bring life.
Now, take water and that doesn't move and look what happens. It becomes stagnant. What once was the source of vibrant life becomes the source of rotten decay and bacteria. Yes, some life can actually thrive in stagnant water, but it is usually the kind of life that feeds off of death.
What in the world does this have to do with your body? Your body is made to move! If we do not use our bodies, our insides become like stagnant water. Toxins build up, things like our joints start to deteriorate. Remember "use it or lose it?" Without movement, life giving blood (like water) can't give nourishing oxygen to areas that may need to heal. Moving keeps us healthy. It keeps us young. Just as water stagnates when it stops moving, so does our bodies. We grow old, we deteriorate. We start to breakdown.
Movement is the key to life. If you have to sit in a chair for most of the day at your job, make sure you find time to move. Take a walk, do some stretches, go play a friendly game of tennis with a friend after work. Find a way to move, to live. You've got one body. If you take care of it, if you use it, it will take care of you. If you don't use it, you are missing out on a great gift.
I'm going for a walk!
