Zip It Up

I wish we all had a body with a zip For when we need a replacement hip The body is unzipped to replace a new part A liver or kidney, a lung or new heart Bones are removed and replaced as required No need for traction or bones that are wired The days will be gone for all operations This will catch on with all the nations Order on-line or a big shop will do To buy a spare body part just for you No need to worry, no need to fuss Decide what you need and catch the bus Tesco’s and Asda can sell the bits you need They will grow organic body parts from a seed So bear that in mind if you are an inventor A brain needs inventing that doesn’t get dementia
