TIL The intensity of sound is measured in decibels (dB), the decibel scale is logarithmic. Basically a 40dB sound is not twice as loud as 20dB one, but a hundred times louder. Also one alarm clock ringing at 70dB, two alarm clocks ringing together don’t hit 140dB on scale but measure 73dB.

TIL that the Vatican is the largest wine consumer in the world per capita. Each resident of the city-state consumes an average of 74 liters of wine per year, or nearly 100 bottles. This is twice as much as in France and seven times more than in the United States.

TIL that ancient Spartan schools deliberately underfed boys to force them to steal food, but severely punished anyone who was caught. This was thought to toughen them up, especially since it accustomed them to hunger, which was common on the battlefield.
