The craziest myth that I've heard about HIV is that you can have "full-blown AIDS" -- like, if you're "full-blown pregnant"!
Either you have HIV or you have AIDS.
Also, the myths of: "Oh, I got HIV." "You're gonna die!" I think that now, in the year 2008, people are really living with the virus because of medication, herbs, acupuncture, reiki, meditation, and I could go on. So many things that are out there -- I can see that people are just living with the virus instead of freaking dying with it, you know?
