Some days it's just better to stay in bed!
I got to thinking about health, and sickness and being well, and how we humans are forever trying something or other to feel better, and if we get sick absolutely positively expect that a medicine be available to cure us, or at least alleviate our symptoms.
In some ways it might be nice to be a dog, and not have to live with the expectations of feeling better than we do. They feel what they feel, and when they don't feel very good they go about their business until they do.
Dogs don't get drunk, don't have hangovers, don't feel sorry for themselves and don't waste time waiting for a miracle cure to what ails them.
They just live.
