I know this idea maybe confusing to many and it's not so much help to any.

But maybe some one can run with this idea and make some new use full things with it.

Basically I propose that humans have a DNA code inside of us to bring forth and create HIV viruses. This sequence is activated when a special key substance enters the cell wall.
Maybe this substance is produced by our glands that in turn is controlled by our brain.

I do not study medicine, this is just a wild idea. Based on our view as humans to see all evil as coming from outside ourselves. Maybe HIV is coming from our inside our own DNA.

I think we can find the sequence that can produce a HIV virus in our DNA to find out if this
is true or not.

Locus that are swarming change appearance before they swarm because they are crowded.
Maybe HIV is first introduced by ourselves when we are subject to something like that as well.

And them HIV spreads the usual known ways.
