If you are really sure you don't care about an item then delete it. If, like me you just can't bear to delete everything like that, then take it out of your regular system, put it in a paper or list and put it in a tickler to re-check in another 5 years.

Some have a lot of project support that I keep gathering for them and so I can't just delete them OTOH I sure don't want them cluttering up my review during times of the year I could do nothing about them.
My SW, Omnifocus, allows both start dates and review times and I use both to handle most of those situations. I have a small DEVONThink note where I pulled the "won't ever do this or don't care" projects that I still have an emotional attachment too and I set a tickler in my Omnifocus system to review that note in 2017 (It's been there since 2012) which will give me the space I need to decide if I am ok with deleting them completely.
