Reminisce, document your own history, or be a tourist in your own town.
Children may not realize that their parents, grandparents, and great-grandparents played the same games that they enjoy. Join your child in traditional games like hopscotch, marbles, tag, leapfrog, or a relay race.
Create a time capsule: Write a letter to your future self about your life now; add artefacts (like a picture of yourself, newspaper headline, an everyday item); place it all in a box and label it to open in 10 years.
Document your personal history for generations to come: Start a journal.
Dress up as a historical figure or put together an outfit inspired by your favorite decade.
