Some things have changed; I hated pears, mushrooms, and bleu cheese as a child, and love them all now. I loved lemonade, but have completely lost my taste for it as an adult.
But two things I don't like have remained ABSOLUTELY constant for 40-plus years:
a) Peas. Hate 'em. Always have, always will. Not dried split peas, or pea pods, just peas. Blech. You'd think I'd have gotten used to them by now, right? Noooooo!l
b) I really don't ribs at all. There is something about the texture of the meat that bothers me. Too....gelatinous, maybe. Pork, beef - makes no difference. Ick. Pulled pork or nothing.
