Every atom you possess has almost certainly passed through several stars and been part of millions of organisms on its way to becoming you.
We each so atomatically numberous and so vigorously recycled at death that a significant number of our atoms – up to a billion for each of us, it has been suggested – probably once belonged to Shakespeare.
A billion more each came from Buddha and Genghis Khan and Beethoven, and any other historical figure you care to name.
