Clearly, I explained myself very poorly. I apologize, let's see if I can arrange something better.
HandsofShadows was wandering about "how old were Erfworld's characters".
You answered that "The oldest person whose age we know of we know of in erfworld is a little more than a thousand turns old, and a turn lasts a day. So... 3 or 4 years old".
Erfworlds unit pop already adult. They don't know what a child is.
In our world, a 15 years old guy is a teenager that doesn't even remember well his childhood... in Erfworld, you have an adult with 15 years of experience in a field of competence. Since their first day of existence, they are "fully" operative, so my point is that we cannot compare erfworld's turns to our world's years.
