What are the chances of me getting aids if i do everything right in my life?

Unlikely: Acquiring HIV is associated with a limited number of activities. Classically, it was a disease of IV drug users, homosexual males and hemophiliacs who had blood transfusions. The infection rate has leveled off, and the rate of heterosexual transmission is stabilizing all due to agressive educational campaigns. Be safe and protect yourself. As far as doing everything right - not possible.
