I hate to pop your bubble here, but a few years ago at a New Year's party a 
person who had cancer go into remission made this statement that she never 
got colds or flus. A doctor I know was there and responded with how not 
getting these sicknesses is a risk factor for cancer! The woman died a last 
summer with the return of her non-Hodgkins lymphoma. 

Hyper-Turing computations or results are not accessible to local observers.
