The blink of an eye. How many blinks a day? Dunno. The speed of light-- that's crazy. There are so many magical systems in place; the world keeps turning, living things constantly growing, the many systems of a living being, the sun continuing to rise for us... and we don't even notice.
Did you ever stop to think that we're actually standing "out" from the earth? We're not really standing up-- that's an illusion. If we looked at the earth from a stellar viewpoint, it might look like a fuzzy ball with so many people sticking out from it. Then again, that would be if we saw it without buildings or trees, etc. because they are all much taller than a person. Even so, next time we stand outside, let's envision us standing out from the planet Earth! Just for fun--
