Passing gas regularly, up to roughly 25 times a day, is normal and signals an active gut microbiome — it's a total absence of gas that would be the thing to note.

This specific point, isolated from the rest of a long unrelated 'signs of longevity' list, broadly holds up against the literature, with a caveat on the exact number. A classic 1990s study put normal frequency at 10±1 times/day, with an upper bound of 20; more recent work using continuous wearable sensors (2025-2026) finds a higher average, around 32 times/day, with enormous individual variation (from 4 to over 170 on the very same diet). The link to microbiome fermentation is well established: a fiber-free diet sharply cuts gas volume, and people eating the most fiber (legumes, vegetables) are statistically among those producing the most gas. '25 times a day' is directionally right but slightly conservative next to the newest data, and the real signal to watch is a sudden change in frequency rather than any single absolute number.

No named source held this one up — that absence is part of the verdict.
