I'm thinking that perhaps traveling by chariot, while better than walking, wasn't a particularly pleasant way to travel long distances.
I htink of armies in chariots, not regular commercial traffic. Riding horseback would be preferable, IMO.
Now I need to look up chariot pictures....
As an elderly skateboarder [17] shot by me last night on campus and his board went the other way, I reflected on chariot riding. I would bet that a charioteer over 21 was a rarity. Most were probably 13-16 and immune to joint ailments.
