Can you imagine how horrible you would feel if you were a pig with swine flu and having to live in conditions like that.
When people get the flu - they feel like they are dying but I am sure there is no way for the animal to let anyone know he is feeling bad or go somewhere to rest up, take the day off and get better.
I can't imagine having to live like that and have the flu on top of it. Perhaps death is a better option to escape this world?
