If your stomach disputes you, lie down and pacify it with cool thoughts.

Cast as folksy advice, the line treats physical discomfort—specifically an upset stomach—as something that can be soothed not only by rest but by mental composure. “Pacify it with cool thoughts” suggests a mind–body connection: anxiety, anger, or agitation can worsen bodily distress, while calm reflection can ease it. In the broader tradition of Paige’s attributed “rules for staying young” and similar maxims, the remark also reads as a metaphor for conflict management: when something inside you “disputes” you, step back, cool down, and de‑escalate rather than forcing the issue. The humor lies in giving the stomach agency, as if it were a quarrelsome partner to be reasoned with.
