My friend Meaghan is an accomplished equestrian, and I’ve been learning some interesting things about horses from her. For instance, despite having the largest eyes of all land mammals, horses have poor eyesight and can see fewer colors than humans. Because of this, they can’t always identify objects on the ground. When they see a pole, they don’t know if it’s a pole they can easily step over or a large snake that might harm them. For this reason, until they are properly trained horses are easily frightened and quick to run away.

We too may want to run from alarming…
