I still have a full deck; I just shuffle slower now.

This quip circulates widely in late-20th- and early-21st-century English as a piece of “senior humor,” often appearing on greeting cards, posters, and social-media posts about aging. It plays on the familiar metaphor of the mind as a “deck of cards” (a “full deck” meaning mentally sound) while acknowledging the slower pace that can come with age. Because it is typically shared as a standalone joke without attribution, it has settled into anonymous folk-quotation status rather than being traceable to a single speech, book, or identifiable first publication.

The speaker asserts continued competence (“a full deck”) while conceding reduced speed (“shuffle slower”). The humor depends on the double meaning of “shuffle”: the literal act of shuffling cards and the figurative sense of moving or processing more slowly. As a compact self-description, it resists stereotypes that equate aging with cognitive loss, reframing the issue as tempo rather than capacity. The line also functions as a socially acceptable way to acknowledge vulnerability—inviting empathy without self-pity—by turning a potentially anxious topic (decline) into a controlled, witty comparison.
