the tangible vs. the real- a tricky EQUATION

The equator is an imaginary line comparable to my childhood friends Sheila and Michelle. However, unlike them, the equator does hold some geographical properties. The latitude of the equator is, by definition, 0°. The length of Earth's equator is about 24,901.5 miles. In relation, the geographical mile is defined as one arc minute of the equator. I think all distance should be measured in time.
The Earth juts out slightly at the equator. It has an average diameter of 12,750 km, but at the equator the diameter is approximately 43 km greater. I learned much of this information from Wikipedia. I hope it is true.

Here are some photos of people at various points on the equator:
