Cast iron is even less "iron" than steel, it's just called that way. Iron is a base metal. Steel is an iron-carbon alloy with the right proportion of carbon, where the carbon makes it harder. "Cast iron" is not iron but it's another iron-carbon alloy with too much carbon, so the carbon makes it brittle.

Some people sure have some strange ideas about how businesses do business. I worked at a Corningware store, and while we did have a fair bit of merch in the back, it was the same stuff we had up front, not like...super secret extra good stuff we kept hidden because...idk? We hate money?

Assuming the time between frames are constant; there is no advantage. Having the GPU output more frames than the monitor can show, just means the monitor will ignore the extra frames. The GPU will do more work and heat your room up faster. So if your room is chilly it might be an advantage, depending what other kind of heating you are using. Most games have a frame limit, vsync or freesync setting, which in their own ways will limit the frame rate to something appropriate.

If you live in the same place for one entire year, you will notice that the sun rises and sets in a slightly different place each day, eventually returning to about the same place it started. I notice this in my own house, because the window from which I can best see the sunset changes through the year! Agriculture, which allowed people to stay in one spot for extended periods of time, made it easier for humans to notice these changes relative to their fixed surroundings.

It wasn't even always that complicated, it is easy to observe the seasons. You always know what season it is because you know what the last season was. You are going to know winter is on its way just based on however many years you have observed it. It wouldn't be like people who didn't keep track of years wouldn't know to prepare for winter. Then you have things like the zodiac, where they simply observed where the sun was in relation to the stars behind it and drew significance with what that might have meant based on the season and significant climate or weather events and so on.
