when did it change that "old people" don't listen to old peoples music anymore. Or was it always/never like that.
like soon everyones grandad will have tattoos. (I know, not everyone. But it is about the answers concept that soon things that were hip and only for young people, those people will be old. And less reversible (in the case of tattoos) than the types of clothes you wear. Because regardless what people wore in their youth, which will inevitably get outdated, people start dressing differently when they are senior citizens)
