Further, if the secret of longevity or even immortality became widely known, then the consequences for the human race would be disastrous.
If you want to control an environment so well that the virii on the people inside that environment are controlled, then maybe. One tear in the environmental bubble or coccoon they are in, well, suddenly they are vulnerable to everything outside, and everything outside is vulnerable to what the people in the bubble had controlling them
In other words, nature would just throw more shit at the "protected" people. Including, from the "unprotected" people. :)
