As a continuation of of the last Forum Repost, Crystal Glacia presents another post for people who happen to be writing a story set in the 1920's. This time, I found a more efficent way to deal with that pesky custom code, so just ignore the underlined asterisks. They're called hottips:
40 (Very) Random Things That Normal People Did Not Have Or Did Not Exist In 1926
Seriously, people have no idea just how important this stuff was. It was regarded as so integral to battlefield medicine, it was a classified military secret until after WWII.
The polio vaccine
(Successful) Large organ transplants
Instant food, such as ramen
They existed; they just sucked
Showers outside the military
Up until the St. Valentine's Day Massacre (1930), you could get a revolver from the Sears catalogue. Seriously.
They're a little Older Than You Think, though- the first one was patented in in the 1940s.
Seriously. It wasn't established until 1927, a year later.
The pill and other contraceptives
Modern deodorants and antiperspirants*
A deodorant called Mum was released in the 1800s, but had to be withdrawn from the market because nobody wanted to admit that they had body odor by buying it. Deodorants and antiperspirants as we know them today wouldn't resurge until 1941.
The last point is...interesting. YOUR TURN: Let's play a game. Can you find out the invention date for as many of these things as possible?
