Interesting subject. I was once told by some uncle that fear of heights is directly related to intelligence. Makes sense, I have very little fear of heights and I'm a bit of a maroon.
I have only one full-scale phobia and it's sharks. Back in 1974, or whenever it was, I was 15 and one of my friends thought that it would be funny to drop some acid and go see this new movie, "Jaws." BIG mistake...we heard that there was a mechanical shark and thought that it would be laughably fake or something, I guess. Scarred me for life. I live in Los Angeles and swim at the beach once in a while but it's always there, the thought of being in the water w sharks.
Other than that, I have a few very minor phobias, almost more like personality quirks. For a long time, I detested going in supermarkets so much that I ate out all meals. I'm talking for decades, either restaurants or quick bite stuff like tacos or a burger. Lots of take-out food brought home. I just really hated going to big supermarkets that much.
It's subsided and during the pandemic in Wisconsin last year, I went to supermarkets all the time and started cooking at home every night. There was no choice because restaurants did not really exist where I was. I even started grocery shopping at Walmart, which has shockingly good groceries and great prices. Could not believe myself.
I also can't valet park my car but I wouldn't call it a phobia. Just OCD.
