Always laugh when you can, it is cheap medicine.

The line treats laughter as a readily available remedy: not a cure for disease in a literal medical sense, but a practical, low-cost way to relieve strain, soften pain, and restore perspective. By calling it “cheap medicine,” the speaker contrasts laughter with expensive or scarce treatments and implies that emotional resilience can be cultivated through ordinary habits. The imperative “Always laugh when you can” also suggests an ethic of seizing small opportunities for joy amid hardship—an attitude often associated with satiric or world-weary sensibilities, where humor becomes a tool for endurance rather than naïve optimism.
