  That’s an interesting question. Took me a few minutes to work it out based on roughly how much of every element there is in the world and we know how heavy an atom of each element is. The answer is:
  134,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000
  
  So quite a lot. And my day is going well thank you, I’ve been teaching university students this afternoon.
