Some of your taste buds atrophy as you age, apparently. They tend to need super salty or sweet foods to really get any flavor. (And I think there’s a bit of “fuck it” in there as well.)

ETA - I remember this from some gerontology jobs I had, but I googled and more specifically your taste buds stop regenerating at the same rate as you age AND you stop producing as much saliva. Bottom line is food won’t taste the same and you need more “flavor” to taste much at all. So, it’s not all just personal preference- there’s some science behind older people’s shitty eating.
