a lot of differences in taste also just come with age, at least for me.
i used to looove really sweet food, like the type of stuff they sell at the supermarket in the "sweets" section. often, these were made mostly of sugar, such as these ones:
now, i can't eat them anymore. i get literally nauseous if i eat even a single piece of them. it's because i cannot bear the intense amount of sugar anymore. it's just because i've gotten older. i prefer potato salad and such nowadays.
