I'd like to ask about an unusual topic that actually reaches back to the Time Gap between How Few Remain and the Great War. Turtledove doesn't mention any character eating breakfast cereal, so it makes me wonder about this: was there a "healthy lifestyle movement" in the US in the 1890s like in OTL? If not, that pretty much means that John Harvey Kellogg, who was ten when the PoD happened, either didn't become a doctor or did but was regarded as a bit of a quack. Any opinions regarding the cereal mogul that wasn't?
And if it's the case that there was no healthy lifestyle movement, then the lack of Corn Flakes isn't the only thing significantly changed. Without the healthy lifestyle movement, there's no moral panic regarding male masturbation that emerged out of it. The moral panic popularized circumcision in the US under the belief that getting cut would "cure" that "problem", and the momentum continues today. So, the question becomes this: In 2021 TTL, are most American men uncircumcised? Or has something else caused circumcising boys to take place? Did someone in Germany figure out that male circumcision helps reduce the transmission of Fleischer’s Syndrome, and did that spark non-religious elective surgery?
And speaking of circumcision...Flora Blackford is a secular Jew married to a non-Jewish man. When she gave birth to the boys, there must have been a little pressure from the Hamburgers to at least do a little something to acknowledge the fact that the boys were half-Jewish. Might Flora have given in to keep peace in the family and called the mohel? Or did future President Blackford get to keep what he was born with?
