Longevity Circle

For reading circles

Discussion prompt deck

Sixteen cards, four themes, one rule: whoever draws reads it aloud and answers first. Every card carries the study it leans on, so the conversation starts from evidence and wanders somewhere personal, which is exactly where a circle does its work.

Print the whole deck for offline circles; the printed sheet includes every card and citation.

Deck

The deck is face down.

16 cards in this deck. Draw one and read it aloud.
