In the landmark paper written by Mervyn Susser and his wife Zena Stein, it was shown that the temporal trends of peptic ulcer were more closely related to the time of birth of individual ulcer patients than to the time when they contracted their ulcer and died from it.1 When the original paper was published in The Lancet in 1962, the overall frequency of gastric and duodenal ulcer were still rising in the British population. The British birth-cohorts born between 1870 and 1890 carried the highest risk of developing gastric and duodenal ulcer, respectively. As these cohorts grew older and their general age-related mortality increased, the overall number of deaths associated with bleeding and perforated peptic ulcers was still rising in the population. Susser and Stein speculated that eventually, as these high-risk cohorts grew older and their proportion in the population declined, the occurrence and mortality of peptic ulcer would
