You’re misunderstanding me.
I’m not saying it’s wrong. I’m saying plagues and epidemics and death, and hatred, etc… are just as common, especially in a medieval setting. Actually, this is WHY the birth rate was that important… because there were so many people dying… at an early age or later. Just have a look at medieval demographics and cause of death. 🙂
For instance, the great plague of Vienna caused 76 thousand deaths and it was just one of many in those times (which weren’t even the middle ages, btw, that plague is from the 17th century).
On the other hand, where a social activity is involved I still believe everything is not okay. If you can be certain only mature adult people will be involved, okay, fine with me, now how can you make sure of that ? 🙂
