Cause and Effect:
I have paid Bill GATES already with the cure for malaria. - One of his pet peeves. I paid him for his part in developing my invention, Artificial Intuition (early 2028). But I also put Mozilla on it so that DOS and LINUX worked in cooperative competition through the Five Cube Sum Number Locks.
Malaria is a little more complex, having five stages in its development. I defeated the human interface at the mosquito. The virus is fine, just devitalize it at the mosquito stage by injecting the signet carried on a frequency in harmony with the female mosquito's antenna.
The only real mystery left is why it is so difficult to find a mosquito when you are actually hunting for one?
