Whenever life gets you down, Mrs. Brown, and things seem hard or tough, and people are stupid, obnoxious, or daft, and you feel that you've had quite enough, just remember that you're standing on a planet that's evolving, and revolving at 900 miles an hour. That's orbiting at 90 miles a second, so it's reckoned, a sun that is the source of all our power. The sun and you and me and all the stars that we can see are moving a million miles a day in an outer spiral arm at 40,000 miles an hour in a galaxy we call the Milky Way.
