Your natural fluids are pure. Avoid fluoridated water, which is a plot of the international Communist conspiracy to sap and impurify our precious bodily fluids. Remember the words of General Ripper: "As human beings, you and I need fresh, pure water to replenish our precious bodily fluids." And above all, beware creationist women; they seek the life essence.
Do I need to avoid creationist women, or should I just deprive them of my essence?
