My View of Senile Dementia

Is apparently wrong.
I thought that as you turned from going normal to going senile
You would start disliking classical music and start liking rap music
Start disliking literature and start liking pulp fiction
Stop listening to R3/R4 etc and start liking pulp fm or crap fm (I’m sure such radio stations must exist somewhere)
Apparently this is not the case
You start liking less of everything more.
That’s all
