Preservation

After watching Chungking Express

Nowadays, most products have an expiry date.
Edible.
Cereal, tuna, baked beans, chocolates, etc
Non-edible.
Cling wrapper, facial cleanser, lotion, etc
But do memories have an expiry date?
If there is,
let the life span be centuries long from the production date.
Because I don't want our beautiful memories to rot.
