Relatively few. Cultures quickly learned that if a person looked at the sun directly or at an abnormal darkening of the sky in fair weather, she or he could go blind from looking at the sun, so they taught generation after generation not to look at the sun in general, and also when the sky darkened abnormally.
Thanks, Pearl. No, it was a joke, which I sometimes make about things from the recent past that a Millennial or Z might not reference. I use AM in my car when I drive near a city for traffic reports. Car makers seem to want to phase it out of their radios to save $3.48 (or some de minimis amount) but some members of Congress want to force them to keep it for emergency radio reports. I wish they would have made them keep the aux input so I can play CD and mp3 playaway audiobooks, but such audiobook formats are being phased out into digital downloads to my phone so that is less of a problem.
