My sister is vegetarian (not even raw vegan) for 20 years, and she constantly tired, its very hard for her to learn new things, yet she still sticks to that diet.
She must not be eating the right things then, Cause I am never tired, I am more aware and lively than I have ever been. My friend who is Raw vegan is a full on body builder...
Also has she ruled out everything else in her life from causing this tiredness?

That doesn't prove it came from Africa at all. It only proves SIV originated from Monkeys. It is still unknown how SIV evolved to HIV.
In fact if you look it up, it is believed that the Bayer pharmaceutical drugs that where contaminated with HIV where because the Monkeys (In US labs) used to harvest the organs from where believed to have SIV... When consumed by humans it gave them HIV, first case being in the US... NOT Africa. This suggests that HIV ended up in humans because of pharmaceuticals NOT naturally.
