The Starpost:
In many classical novels describing the Dobenzin era, the horses of the heroes are driven and die, or the heroes worry that if they do not rest, they will drive horses and lose them. Question: How does it happen that a horse dies simply from overstress, and not, for example, refuses to jump further? After all, a long-running person will get stuck, will feel a crack in the side, but just resting will recover. How much should a horse jump to get tired? I have eaten a horse from the bank, but I do not own horses.

Yyy: Childhood spent on the ranch of the grandfather of the horse farmer?
XXX: No, in the athletic section.
