Even if it isn't specifically helpful, it's probably good practice for staying aware of what I'm handling and potential confidentiality/consequences.

An old job had an industrial shredder so I'd pile it up and take it there. Then we had a smaller home shredder but that got annoying. Now I just cut out and sliver the PII parts with scissors but that seems silly when all that info is out there, hence the junk mail.
