Common entertainment included playing cards. However, there was a tax levied when purchasing playing cards but only applicable to the 'Ace of Spades.' To avoid paying the tax, people would purchase 51 cards instead.

Personal hygiene left much room for improvement. As a result, many women and men had developed acne scars by adulthood. The women would spread bee's wax over their facial skin to smooth out their complexions. When they were speaking to each other, if a woman began to stare at another woman's face she was told, 'mind your own bee's wax.' Should the woman smile, the wax would crack, hence the term 'crack a smile'. In addition, when they sat too close to the fire, the wax would melt . . . Therefore, the expression 'losing face.'
