Mind viruses infect your mind, programming you with directions that point you away from where you want to go. Since this happens unconsciously, all you're aware of is that as you grow older, life becomes more stressful, less fun, more of a drag, and less meaningful. You may feel your motivation slipping away. You may get less excited about things than you used to. These are some of the effects of infection by a virus of the mind, an infection you can't avoid entirely short of living in complete isolation from birth.
