@rew – No offense taken at all. I guess you could say I am a little bit of an amateur historian. Just something I do on the side. Not a super expert by any means.
These types of things you never learn in school. In history class they just concentrate on the major events like wars, disease, different kings, etc. They don’t focus on the daily life of these civilizations. If you look more in depth though you will see that this is true.
