Apologies, but we have had to remove your submission. We ask that questions in this subreddit be limited to those asking about history, or for historical answers. This is not a judgement of your question, but to receive the answer you are looking for, it would be better suited to /r/AskScience.

If you are interested in an historical answer, however, you are welcome to rework your question to fit the theme of this subreddit and resubmit it.
