Can't find a thing but I have some other ideas:
Get something that was made the year he/she was born
Get a copy of a newspaper of the day he/she was born and from their hometown.
Make an $80 donation in their name to their favorite charity.
A coin from the year of their birth
A gift basket with 80 items (favorite foods, pieces of candy, etc.)
A jar of 80 slips of paper containing each containing a memory of time with the person.
A bouquet of 80 flowers.
I have great fun doing this! If you need more info, let me know. If not, please hit the "ACCEPT" button.
