Mickey Mouse never dies because he's taking every drug from the experiments that only work in mice

90% of pharma 'candidate' drugs fail humans trials after they're shown to work in mice. That means we invent 10 premium mouse drugs for every human drug. So where are all these healthy mice? Most only live up to 2 years old. Mickey Mouse just turned 97 and has barely aged. Is anyone looking into this? They are inventing these treatments to keep him alive. Life's pretty good if you're a rich mouse.
