3. The most played song on AM radio of all time “You’ve Lost That Lovin Feeling” has a runtime of 3:45 which at its release was considered as too long for AM radio. In order to secure airtime, Phil Spector had a false running time (3:05) printed on the label to trick DJs into playing it.

For millennia Autism and other sudden disabilities was explained by the Changeling folklore. A fairy or demon would steal a normal baby and replace them with their own child in disguise.

17. In the Middle Ages, Catholic women were prohibited from having sex on Sundays, Wednesdays, or Fridays, on feast days, while fasting for Lent or Advent or while "impure" (menstruation, pregnancy, 40 days after giving birth & while nursing). Everything but the missionary position was considered sodomy.
18. In the 50s, teenagers having a stable monogamous relationship (“going steady”) was considered edgy and frowned upon by parents and the church as amoral.

The rationale behind this was that going steady would encourage the relationship to develop into one of physical intimacy, something parents wished to avoid.
19. For the Romans, a big penis wasn’t seen as a sign of manliness or sexual skill. All of the Roman heroes - mythological, political, or athletic - were portrayed as having small, compact genitalia, almost like pubescent boys. What we consider “well-endowed” was considered a sign of a barbarian or a fool.
20. Seat belts were very controversial when they first appeared in cars during the 40s and 50s with many arguing that they caused injuries and didn’t work, no matter how much researchers disputed these claims. Many people refused to wear them and even cut them out of their car seats.
