I think people’s tastes are largely set in childhood, or as a teen or young adult at the latest. If you decide you hate something when young, it is rare you can change that in later adulthood. You won’t even be inclined to give it a chance.
Don't know about that. I used to drink coffee "light and sweet" from the deli, which Starbucks and DD turned into an industry. Now it BLACK only, and the darker the roast the better.
When I was a kid, I wouldn't eat the sauce and cheese on a pizza. I would scrape it off and just eat the crust. In my teens and beyond I became a cheese pie connoisseur and NY pizza bigot.
Also, I would never eat broccoli, now I love it.
