I feel about airplanes the way I feel about diets. It seems to me that they are wonderful things for other people to go on.

In a characteristically wry, self-deprecating style, Kerr compares air travel to dieting—two modern “improvements” widely praised as sensible and beneficial, yet often experienced as uncomfortable, restrictive, or anxiety-inducing. The joke turns on admiring the idea in principle while wanting others to do the actual enduring. Beyond humor, the line gently punctures social pressure to embrace whatever is deemed healthy, efficient, or progressive, suggesting that enthusiasm for such regimes can be more performative than heartfelt. It also captures a mid‑century domestic-comedy sensibility: skepticism toward fads and a preference for ordinary pleasures over disciplined self-optimization.
