I think it plays out a little something like this:

Dying Patient: Dr...you gave me only a few weeks to live as no therapy is working and I'm a mother of 3 young children. Isn't there anything else I can try? Anything at all? I don't know anything about science, but I am desperate!!

Dr: Well, probably not, because according to Darwin I have something that shouldn't exist, so I cannot wrap my head around it, but...

Dying Patient: With all due respect, Dr, "f" your head and give me the damn drug!
