I have learned not to accept simplistic models or equations as "real life". My father was an electronics engineer. I am a biologist. He didn't like biology as a science, too mushy. And the mushiest is ecology. Gotta take in the whole, not a sampling nor a more simplifying equation. Consider when California rarely had a Gray Whale sighting, we didn't have starving sea lion pups. Not we have several species of off coast whales and lots of starving sea lion pups. No one connect the dots. Gotta look at the big picture. Equality: Your explanations do not. Moi r > g
