As always with this feature, the _floss is not responsible for accuracy. If you know one of the below statements/links to be untrue, by all means, let the world know in the comments below.
Today I typed in "common 100 years ago" unearthing the following:
Illegitimacy and extra marital affairs were just as common 100 years ago as they are today, our forebears were just more adept at keeping them secret.
Single parenting was just as common 100 years ago as today.
"Some seven men form an association", in the rarely-performed Gilbert & Sullivan operetta Utopia Limited, is often quoted by legal writers as evidence that corporate fraud was as common 100 years ago as it is today.
Essay tests were common 100 years ago, but they were too expensive to give to everybody everywhere. That's why they were replaced by machine-scored multiple choice tests.
Smoking is no more acceptable than chewing tobacco and spitting on the floor - a habit that was very common 100 years ago and would horrify people now.
Adults being unable to read was common 100 years ago, and not that rare 50 years ago. But, despite the hand wringers who bash our public schools, I have yet to meet an adult in america who could not read and I am 40 years old.
