The older I get I have become a never-satisfied sponge for information. I used to think, well, I'll look that up when I get to a library. Now it's all on the net. History, science (especially geology, physics, and the universe), and news. And then there's the car stuff, whether it's car investing, car repair, performance, etc. This was the "diversivied stimulation patterns." Probably why I ask so many questions. I picture myself on Jeopardy I guess.
I go to sleep and wake up watching science facts. This morning I learned about the Vesuvius volcano and later the Sahara Desert. The red sunsets in Florida are caused by dust from the Sahara. The pyramids are built with limestone blocks. Limestone is formed by dead calcareous marine life falling to the bottom of the seas. So the Sahara was underwater for millions of years. Also, the big oil fields in the Middle East had to come from buried plants and animals in a near-shore environment.
