Why are old people so obsessed with reading obituaries?

I was over at my parents and noticed they were reading obituaries online. apparently there is a site where you can find "local " obituaries. there not even reading ones for people they knew , just random people who passed away?

is this normal? I know obituaries have been popular in newspapers for some time but to read ones online for people you didn't even know? starts to seem a bit off or is it just me?
