After the great war, many things changed, especially for women – who started smoking in public. Their bathing suits got shorter and younger women (in their 20s) started to show off a new identity.
Also, swimming as a sport became huge in part because of cinema news and commentaries from the Berlin Olympics in 1936.
Apparently young people have fun telling “poor suckers” that they’ve beaten swimming world records. And those armed with goggles search calm waters in the morning for lost jewelry and rings.
