Then you start your IV and draw your blood. Then when your done you can quickly release it by pulling the string that is left out from the loop and done!

<em>Everyone should care.</em>
<em>No one should ignore a world so</em>
<em>Vital and green;</em>
<em>Inviting and teeming with life. Mother earth</em>
<em>Revolves around our respect, how we take</em>
<em>Ownership of our actions; and</em>
<em>Never forget our inheritance. We must</em>
<em>Mind our responsibility and pass along</em>
<em>Every moment of beauty bestowed upon us;</em>
<em>Nurture a green future for our children, and</em>
<em>Try to preserve Mother Nature's gift to us all.</em>
