Isn't snoring something humans and other animals would have lost through the evolutionary process given that snoring gives away your location and signals to potential predators that you're asleep and not able to defend yourself? (Asking for my wife)

Why don't they put the wires much closer together on powerlines rather than separated so far apart? It would be so much less unsightly if they ran together in one line or very near each other rather than spaced out 10 and 15 feet apart down the pole. Is there an engineering/science reason for this?

I calculate that in the year 1520 or so, there were more than 1 million people on earth who were my ancestors. Am I wrong? I figure each generation is around 25 years so that's 20 generations back to 1520. 2 times 2x2x2x2 etc. i.e, 2 to the 20th power is a little over 1 million. Is that possible?
