Has anyone else noticed that the characters are far healthier and live far longer than expected for the timeframe? I am about to broach the 13th century and have never had a ruler died before the age of fifty and my court is filled with an awful lot of old codgers doddering about. The most sprightly oldster I've seen thus far was Tancred d'Hautville, my gay marshal, who lived to the ripe old age of 96, outliving 4 rulers and leading troops till his dying breath.
Check out the kings, queens, churchmen, literary figures, and composers of the period. Those that didn't die in infancy, from plague or in the battle often lived very long lives. Here, for example, are six of the most respected composers:
Johannes Ockeghem: 1410/25--1497
Josquin Desprez: 1440/5--1521
Orlando de Lassus: 1530/2--1594
Guillaume Dufay: 1397--1474
Gilles Binchois: 1400--1460
John Dunstable: 1390--1453
These names aren't "cherry-picked," but are simply six of the outstanding, most highly regarded musicians of their times. Most were also members of the clergy, though only in the sense that it was required to serve in a specific court capacity--and that it meant they could receive the proceedings from prebendaries and the like (a sort of sacred equivalent of secular landlordism) upon gift from a ruler.
This kind of thing was much more common than popular myth would have us believe.
