I wonder if people had a more fatalist attitude what with the Black Plague killing a quarter of the population. Or maybe the fact that a large proportion of the adult population were twenty somethings with raging hormones and carrying knives.
The average life expectancy for a male child born in the UK between 1276 and 1300 was 31.3 years. In 1998, it is 76.
However, by the time the 13th-Century boy had reached 20 he could hope to live to 45, and if he made it to 30 he had a good chance of making it into his fifties.
@yaypie Does your game have any notes on the root cause of this behavior?
