Why is the "BlyssPluss" pill called BlyssPluss?

Crake explained that Paradice focused on two main projects. The first involved the creation of a pill, BlyssPluss, which eliminated many of the non-biological causes of death. In other words, it removed misplaced sexual energy. Crake saw this as the main indirect cause of death. The pill accomplished this by protecting the user from diseases, providing an unlimited libido, and extending youth. Crake explained that the pill would also serve as a permanent form of birth control.
